fig1 is a generalized block diagram illustrating implementing a shop - with - a - friend (“ s . w . a . f ”) system in conjunction with a social network . the s . w . a . f mechanism is comprised of a “ s . w . a . f . engine ” 100 , the s . w . a . f engine residing on servers accessible to a client via a web - browsing mechanism ; and , a “ s . w . a . f client engine ” 111 , residing on a device accessible to the user and communicating with the s . w . a . f server engine 100 over a network ( e . g . the internet .) in the present example , users “ person 1 ” 104 b , “ person 2 ” 104 c , “ person 3 ” 104 c may be using a system which utilizes the s . w . a . f server engine 100 . for example , users 104 a - 104 c may be on one or more websites tied into the s . w . a . f engine 100 . the s . w . a . f engine 100 may utilize a data - store 101 , e . g . a database , containing , among other data , data pertaining to the users 104 a - 104 c . the client s . w . a . f engine 111 may receive information from the s . w . a . f engine 100 , via communication channels 110 a - 110 c . in this example , for illustrative purposes only , the communications channels 110 a - 110 c may correspond directly with the users 104 a - 104 c , respectively ( e . g . communications channel 110 a may carry information pertaining to “ person 1 ” 104 a .) a user 116 may be connected to the s . w . a . f server 100 via a s . w . a . f client component 114 , communicating with the s . w . a . f client engine 111 . the s . w . a . f client engine 111 may receive information pertaining to all users connected to the swaf server 100 : “ person 1 ” 104 b , “ person 2 ” 104 c and “ person 3 ” 104 c . the information received by the swaf client engine 111 may be further filtered to include only users who are “ friends ” ( the definition of a “ friend ” defined by a social network ) of the user 116 on the social network 106 , accessible by the swaf client engine 111 . the information received via the swaf engine 111 , via channels 110 a - 110 c , corresponding to the users 104 a - 104 c , may be further filtered by the swaf client engine 111 to present the user 116 with information pertaining only to his / her friends , as defined in the social network 106 . in one possible embodiment , the user 116 may only see ( i . e . have access to , be able to interact with , etc .) “ person 1 ” 104 a and “ person 3 ” 104 c , because these people have profiles in the social network 106 ( as “ friend 1 ” 108 a and “ friend 3 ” 108 b ) and because these people are friends of the user 116 in the social network 106 . in another related possible embodiment , the users “ person 1 ” 104 a and “ person 3 ” 104 c may be able to see and / or interact with the user 116 , via the swaf mechanism , by virtue of being friends on the social network 106 . in other possible embodiments , various other rules may be implemented , and options presented to users , allowing , disallowing and limiting electronic interactions via the swaf mechanism , based on social network relationships and other factors . fig2 a and 2 b are generalized block diagrams illustrating architecture of a s . w . a . f mechanism , in one possible embodiment . a website 200 may communicate with a social network 250 ( e . g . facebook ®) each user commences interaction with the website 200 by visiting the website &# 39 ; s 200 url ( i . e . web address , e . g . www . amazon . com ) the website 200 may allow the user to log into the social network 250 by using the user &# 39 ; s social network 250 credentials . once the user has logged into their social network 250 profile , the website 200 may gain access to the user &# 39 ; s social graph , including the user &# 39 ; s list of friends , etc . the website 200 may be rendered on the user &# 39 ; s electronic device via a web - browsing application ( e . g . internet explorer ®, chrome ®, safari ®, etc .) in rendering the contents of the website 200 , the user electronic device &# 39 ; s web - browsing application may create a document 202 containing user - sided - representation of the website 200 . the document 202 may contain dom elements ( document object model ) accessible programmatically and visible to the user . for example : dialog boxes , input fields , buttons , etc . the document 202 may contain ( or have access to ) a s . w . a . f document engine 230 . the s . w . a . f document engine 230 may be a library of javascript and / or jquery code which facilitates communication between the document 202 and its elements , and a s . w . a . f server engine 240 , which in turn , facilitates communications with remote users and their documents . the s . w . a . f server engine 240 may be written in a server - side coding language ( e . g . php , ruby on rails , c ++, java , etc .) and communicate with the s . w . a . f document engine 230 . the communication between the s . w . a . f document engine 230 and the s . w . a . f server engine 240 may be facilitated using ajax ( asynchronous javascript and xml ), or any other protocol . the s . w . a . f server engine 240 may communicate with a data store 242 , the data store 242 storing records on users &# 39 ; live usage of the s . w . a . f system , including , but limited to , a period heart - beat from each user &# 39 ; s s . w . a . f engine and instructions sent from one user to another . referring now to fig2 b , the document 202 , displayed in the user &# 39 ; s web - browser , may contain elements 255 ( e . g . a button , an input field , a selection field , a drop - down box or any other object displayed on a website ). the s . w . a . f document engine 230 may contain modules for facilitating synchronized communication between documents used be two or more remote users . one module may be a function for processing outgoing messages 232 . the function for processing outgoing messaging 232 may communicate with elements 255 in the document 202 , specifically querying their state and responding to events generated by the elements 255 . the function for processing outgoing messages 232 may then transmit messages reflecting changes in the elements 255 , onto the s . w . a . f server engine 240 . for example , the element 255 may represent a button invoking a “ purchase ” function in the document 202 , while the document 202 represents a page in the amazon . com ® website depicting a certain item . in this example , in response to a user &# 39 ; s clicking the “ purchase ” button associated with the element 255 , the function for processing outgoing messages 232 may create an electronic message depicting the clicking action , and transmit it , via ajax , onto the s . w . a . f server engine “ nexus ” system 240 . another module within the s . w . a . f document engine 230 may be a function for processing incoming messages 234 . the function for processing incoming messages 234 may receive and process from the s . w . a . f server engine 240 , messages affecting elements in documents in other users &# 39 ; web browsers , and invoke corresponding action on elements 255 on the present document 202 . for example , the s . w . a . f server engine 240 may contain an electronic instruction to invoke a “ purchase ” button within a document in the user &# 39 ; s browser , the electronic instruction generated by a remote user clicking a corresponding “ purchase ” button on their web browser . the function for processing incoming messages 234 may receive the message from the s . w . a . f server engine 240 , and may then send a “ click ” instruction to the corresponding element 255 ( i . e . “ purchase ” button in this example ) on the user &# 39 ; s local browser . fig3 a - 3 e are generalized block diagrams illustrating database architecture in an implementation of a s . w . a . f system , according to one possible embodiment of the present invention . due to the fact that users &# 39 ; browsers are not able to communicate with each other directly , a database 310 may be utilized to broker communication between various web browsers . user1 and user2 may utilize webbrowsers that include s . w . a . f modules 300 and 302 , respectively . the s . w . a . f modules 300 and 302 may communicate with a s . w . a . f server 308 , which in turn , may store information in a data store 310 . the s . w . a . f modules 300 and 302 may be embedded in a hosted website 306 , which in turn communicates with a social network 304 . for example , the website 306 may be www . zebedo . com , www . amazon . com , http :// apps . facebook . com / shopzebedo , etc . and may allow a user access to a social network 304 , such as facebook ®. the system depicted in this illustration allows multiple users accessing the same website 306 to synchronize their viewing and using the website 306 from different browsers . the data store 310 may contain records containing s . w . a . f - related information on the users user1 and user2 , form the s . w . a . f modules 300 and 302 associated with those users . in a presently - preferred embodiment , the data store 310 may contain a row of data in one table per user . the data store 310 is illustrated here containing two rows of information : a top - row containing data - elements 312 a - 312 d , associated with user1 &# 39 ; s s . w . a . f module 300 ; and , a bottom - row containing data - elements 314 a - 314 d , associated with user2 &# 39 ; s s . w . a . f module 302 . in this example , the “ bizid ” column contains value “ abc ” 312 a corresponding to user1 &# 39 ; s s . w . a . f module 300 , and value “ abc ” 314 a corresponding to user2 &# 39 ; s s . w . a . f module 302 . in cases where one single s . w . a . f instance is handling two or more websites / businesses , it may be advantageous to identify each s . w . a . f database 310 record with a unique business id to insure users on different websites are not able to shop together , while on different websites . in this example , the “ uid ” column contains value “ 12345 ” 312 b corresponding to user1 &# 39 ; s s . w . a . f module 300 , and value “ 6789 ” 314 b corresponding to user2 &# 39 ; s s . w . a . f module 302 . similarly , the “ uname ” column contains value “ user1 ” 312 c corresponding to user1 &# 39 ; s s . w . a . f module 300 , and value “ user2 ” 314 c corresponding to user2 &# 39 ; s s . w . a . f module 302 . values in the database 310 may be updated via a “ heartbeat ” periodic message , e . g . of initial frequency of 3 hz , transmitted by the s . w . a . f modules 300 and 302 , populating corresponding database rows , including last - checkin - timestamps 312 d and 314 d . all database communications may generally be originated by the s . w . a . f modules 300 and 302 , transmitting messages to the s . w . a . f server engine 308 , which writes information into the database 310 , reads information and transmits relevant information back to the s . w . a . f modules 300 and 302 . heartbeat ( or synch ) frequency may be set to vary depending on state of connectivity . for example , “ idle ” frequency , i . e . when user is not connected via a s . w . a . f session to any other user , may be set to 3 hz . when sending a connection request and awaiting a reply , the heartbeat frequency may be increased to 1 hz . when connected to a remote user via a live s . w . a . f joint - shopping session , the synch frequency may be increased to 0 . 2 hz ( to allow for smoother , more real - time synchronized action between users , for example , when one user clicks on a button , the corresponding button on the other user &# 39 ; s screen should experience a click almost at the same time .) when a s . w . a . f live shopping session is terminated or discontinued , synch frequency may decreased to consume less system resources . in one preferred embodiment of the present invention , “ stale ” records ( e . g . records older than 2 minutes ) may be cleared up by the s . w . a . f server engine 308 when the latter is called by any of the s . w . a . f modules 300 and 302 . in other potential embodiments , the database 310 may be “ self - cleaning ”, i . e . delete own stale records ; or a service / process within , or outside of the s . w . a . f server engine 308 , may clean stale database records . referring now to fig3 b , the s . w . a . f modules 300 of user1 may query the “ user2 row ” ( 314 a - 314 d ) of the database 310 , via the s . w . a . f server engine 308 , and display to user1 information 316 pertaining to user2 ( e . g . user2 &# 39 ; s name and any other pertinent information .) similarly , the s . w . a . f modules 302 of user2 may query the “ user1 row ” ( 312 a - 312 d ) of the database 310 , via the s . w . a . f server engine 308 , and display to user2 information 318 pertaining to user1 . this functionality may allow a user to see what other users are “ present ” at a given store in real time , and engage in a live interactive session with them . referring now to fig3 c , user1 may choose to initiate a live s . w . a . f session with user2 . user1 &# 39 ; s s . w . a . f module 300 may transmit a message to the s . w . a . f server engine 308 , which in turn may place a request for connection 320 a and 320 b , in “ user2 &# 39 ; s row ” in the database 310 . in one possible embodiment , the message may be comprised of the requesting - user &# 39 ; s - uid “ 12345 ” 320 a , and an instruction representation request to connect “ connectrqst ” 320 b . as the s . w . a . f modules 302 of user2 performs periodic heartbeat - read / writes into the database 310 , via the s . w . a . f module 308 , the s . w . a . f modules 302 may read the request - to - connect instruction 320 b ( as well as all other associated connection request information from user2 &# 39 ; s row / record in the database 310 ) and may display the information 322 to user2 ( e . g . “ user1 wishes to shop with you , would you like to accept ?”). user2 may then accept or reject the invitation . referring now to fig3 d , in a case where user2 has accepted the request from user2 , user2 &# 39 ; s s . w . a . f modules 302 may populate user1 &# 39 ; s row ( 312 a - 332 a ) in the database 310 with information confirming acceptance of the connection , etc . user1 &# 39 ; s s . w . a . f module 300 may then read that information , causing it to display 326 to user1 connection information . likewise , user2 may see similar connection information 324 . once s . w . a . f connection has been established between user1 and user2 , referring now to fig3 e , actions performed by one user may be automatically performed by the s . w . a . f mechanism for the other user . for example , a web browser used by user1 and displaying web content , may contain an element 350 ( e . g . a button in this illustration , but generally an input field , a drop - down box , a youtube ® video control element , etc .) an element &# 39 ; s click event ( e . g . button 350 being clicked ) may trigger the s . w . a . f module 300 to process the click - event and transmit a message to the s . w . a . f server engine 308 , causing the latter to write into the database 310 record of user2 , an instruction to generate a click of the corresponding element / button within user2 &# 39 ; s web browser . the instruction may include information such as “ 1 | clicked ”, where the “ 1 ” represents the element clicked , and the “ clicked ’ represents the action . in related embodiment , and elements name / id or any other information delimiting an element on a document , may be used . the instruction may be received by the s . w . a . f module 302 of user2 , when the latter queries the s . w . a . f server engine 308 for new pending messages . in addition to receiving the instruction , the s . w . a . f module 302 may process the instruction and execute a command within its web - browser document — in this case , generating an instruction to “ click ” button 352 . the resulting effect is that user2 , while passive ( i . e . not clicking the button 352 ) may observe that the button 352 is clicked automatically . in addition , the clicking of the buttons 350 and 352 may initiate a similar action for both users on their corresponding web browsers . for example , if both users are at an amazon . com ® virtual store , clicking the button 350 may initiate a purchase - flow for user1 . however , as user1 and user2 are connected via the s . w . a . f mechanism , button 352 may be automatically - clicked for user2 , also initiating a purchase - flow for user2 within user2 &# 39 ; s web browser . fig4 is a generalized block diagram illustrating an ability of a user to preview activities of other users , via a s . w . a . f mechanism , in one possible embodiment of the present invention . a user who is not - yet connected to any other user in a s . w . a . f session , may be privy to at least information regarding other users — e . g . friends — who are at a website that is part of a s . w . a . f system . user1 400 , user2 402 a , user3 402 b and user4 402 c , may be on one or more website &# 39 ; s that is part of a s . w . a . f system . these users may be at different geographic locations , accessing the website ( or websites ) from various different types of electronic devices and different web browsing applications . further , these users may be viewing different things on the websites ( s ). for example , one user may be reading reviews on cameras , whereas another may be choosing a specific shoe in the right size . a system that is s . w . a . f - enabled is “ aware ” of the activities of each user via a s . w . a . f client engine that is active within a document displayed in the browser of each user , and which communicates with a s . w . a . f server engine . for example , users 402 a - 402 c may access a website via browsers 404 a - 404 c , respectively . the browsers 404 a - 404 c , may display web content that includes s . w . a . f client engines 406 a - 406 c , respectively , which may in turn , communicate with the s . w . a . f server engine 410 . similarly , user1 400 may browse a s . w . a . f enabled website whose content includes the s . w . a . f client engine 412 , also connected to the s . w . a . f server engine 410 . accordingly , one or more of the s . w . a . f client engines may present their corresponding users with information pertaining to other users &# 39 ; current browsing activities . for example , in the illustration of fig4 , user2 402 a and user3 402 b are engaged in a joint - shopping session , and user4 402 c is shopping for an iphone . accordingly , user1 400 may be notified of users 2 , 3 , 4 &# 39 ; s activities , for example “ user2 is shopping together with user1 ” 414 or “ user 3 is looking at an iphone ” 418 . further , user 1 400 may be prompted to connect to any of the other users . in one presently - preferred embodiment , the connection may be facilitated with a single click on notifications 414 or 418 , connecting to a live s . w . a . f session with users 2 and 3 or user 4 , respectively . in various possible embodiments of the present invention , various privacy considerations may be implemented to control and limit users &# 39 ; view into other users activities . for example , but not limited to : allowing view only into activities of facebook friends and / or allowing a user to specify a global setting on whether their shopping activities may be viewed , and / or allowing a business to specify rules , and / or allowing users to select specific friends / stores / items which may be visible to others , etc . fig5 a & amp ; 5 b are generalized flow diagrams illustrating dynamic pricing in a system incorporating s . w . a . f technology , in once possible embodiment of the present invention . merchants may offer groups of buyers discount pricing , especially in situations where a friend - brings - a - friend and all can make a decision at one time . friends may also influence friends to buy a certain brand . for example , if four friends are co - shopping trying to collectively decide on running shoes , debating between nike ® and other brands , nike ® may decide to offer an instantaneous discount to all four friends if all commit to buying together . at step 500 , a user may enter a s . w . a . f - enabled website , for example amazon . com ®. in the prior art , at step 502 , price for each item ( s ) may be calculated and presented to the user at step 504 . for example , “ panasonic 40 in led tv $ 500 ”. at step 506 , a second user , user2 , may enter the same store . at step 508 , it may be determined whether user2 is connected via s . w . a . f to user1 ( e . g . user2 has clicked on user1 &# 39 ; s picture and requested a shop - together experience , and user1 accepted .) if at step 508 it is determined user1 and user2 are not connected via a s . w . a . f session , user 2 would be displayed the same pricing as user1 ( i . e . “ panasonic 40 in led tv $ 500 ”). if at step 508 it is determined user1 and user2 are connected via a s . w . a . f session , at step 512 , special “ discounted group pricing ” may be computed for both user , and at steps 514 a and 514 b , users 1 and 2 , respectively , may be presented with the discounted price ( e . g . “ panasonic 40 in led tv $ 450 , 10 % discount ”) in various possible embodiments of the present invention , various business rules may apply , such as allowing discount only if both users commit to a purchase ; usage of variable pricing / discounts etc . in addition , other users at the virtual store , not shopping together via s . w . a . f , may see other , e . g . standard , pricing . conversely , discount levels may be automatically adjusted downwards when less users are shopping together via s . w . a . f . if at step 520 it is determined that users1 and 2 are disconnected , e . g . at step 518 a user2 leaves the store / website ; or at step 518 b user1 and user2 become disconnected / choose to terminate shopping together , at step 522 the discount pricing may be rescinded for one or both users . as result , at steps 524 a and 524 b , users1 and 2 , respectively , may automatically see pricing revert to original pricing , i . e . “ panasonic 40 in led tv $ 500 ”. in a related - possible embodiment of the present invention , users may be presented with “ teaser pricing ” should they invite their friends to shop together . for example , referring now to fig5 b , at step 506 user2 may enter the same virtual store as their friend , user1 . at step 508 , it may be determined whether user1 and user 2 are connected via a s . w . a . f mechanism , i . e . are co - shopping . if at step 508 it is determined the two users are not already shopping together , at step 550 it may be determined whether user1 and user2 are friends ( e . g . as defined by a social network such as facebook ®, wherein friendship is discerned from the users &# 39 ; social graphs .) if it is determined at step 550 that user1 and user2 are friends , at step 552 proposed group - discounting may be calculated and presented to the user at steps 554 a and 554 b . for example , at step 554 a , user1 may see a pop - up notification to the effect of “ your friend , user2 , is available to shop together . invite her and you will each receive a 10 % discount on purchases .” in a further embodiment , user1 may click on the pop - up to automatically invite user2 to shop together via the s . w . a . f mechanism . fig6 is a generalized block diagram illustrating a s . w . a . f enabled system wherein a social - network “ invite friends ” control facilitates a one - click co - shopping experience between two users , in one possible embodiment of the present invention . social network feature common controls , such as facebook ®&# 39 ; s “ send ” and “ share ” buttons , which allow a user to see a list of their friends , select one or more friends from the list , and send them a message through the social network . in the prior art , a friend receiving a message may click a hyperlink embedded in the invite - message and be taken to a different location ( commonly the application / web - address from which the user had sent the invite .) user1 612 a may access a s . w . a . f - enabled website 600 ( e . g . www . amazon . com or a facebook ®- application such as http :// apps . facebook . com / shopzebedo ) user1 &# 39 ; s web - browsing application , used to access the website 600 , may contain a document 602 a ( a document generally refers to the content of a webpage rendered inside a user &# 39 ; s browser , based on web content from a website .) the document 602 a may contain user - accessible elements and controls such as the facebook ® “ send ” button 604 . upon clicking the “ send ” button 604 , user1 612 a may be presented with a list of one - or - more social - network 608 friends . user1 612 a may select a friend , e . g . user2 , and send user2 612 b an invite via the social - network . in the prior art , an invite message 610 from a friend may be displayed on a wall associated with user1 and / or user2 in the social - network 608 ; or in a newsfeed of user1 and / or user2 ; or as a chat - message to user2 , etc . user2 612 b may select the invite message 610 displayed , and automatically be displayed the website 600 via his / her web browser , in the prior art . in a s . w . a . f - enabled system , upon launching the website 600 , user2 612 b may be automatically connected to a s . w . a . f system , illustrated herein as comprising components 606 a , 606 b and 620 . the s . w . a . f server engine 620 may broker a s . w . a . f connection between user1 612 a and user2 612 b , via s . w . a . f document engines 606 a and 606 b , respectively . in one preferred embodiment of the present invention , the invite message 610 may content a unique token , e . g . “ 123 ”, which may uniquely represents user1 &# 39 ; s invite of user2 to website 600 . the s . w . a . f document engine 606 b of user2 612 b may transmit the content of the token , e . g . “ 123 ”, to the s . w . a . f document engine 606 a of user1 612 a . in response , the s . w . a . f document engine 606 a of user1 612 a may automatically initiate a connection with the s . w . a . f document engine 606 b of user1 612 b ; and , the s . w . a . f document engine 606 b of user2 may automatically reply accepting the s . w . a . f joint - shopping invite . in effect , user1 may use facebook ®&# 39 ; s “ share ” or “ send ” or any other social plug - in to invite user2 ( via posting on own wall , user2 &# 39 ; s wall , in a chat , newsfeed , etc ) user2 may then click on the invite and be presented with the web portal of the website from which user1 had sent the invite . user1 and user2 would then be automatically connected to each other via a s . w . a . f joint - shopping session . fig7 is a generalized block diagram illustrating a s . w . a . f system augmenting a website , in one possible embodiment of the present invention . a non - s . w . a . f website can be enhanced with s . w . a . f - enabling components , allowing the website to facilitate co - browsing / shopping among users . a website 700 , representing a non - s . w . a . f website , typically includes a main web - accessible file , e . g . “ index . php ” 710 , accessible to users user1 and user2 using web browsers 704 and 706 , respectively ( e . g . when a user navigates to website &# 39 ; s 700 url , e . g . www . amazon . com , a main page such as index . php is typically accessed first .) in common implementation in the prior art , the website 700 main page “ index . php ” 710 may contain two types of code : code for server - sided execution 712 , and code for client - sided execution 722 . the server - sided code is typically in the form of php , c ++, ruby on rails , jave , etc . the client - sided code is typically javascript . in the prior art , although user1 and user2 are both accessing the website 700 , they are unaware of one another , and have no means of interacting . for example , if website 700 is amazon . com ®, user1 may be accessing amazon . com ® from an iphone to purchase a camera , whereas user2 may be accessing amazon . com ® from an android - based device to browse for books ; however , all the while , user1 and user2 are unaware of each other &# 39 ; s presence and are unable to shop together . in one preferred embodiment of the present invention , the website 700 may be augmented with s . w . a . f technology , allowing user1 and user2 to co - browse / shop . further , the s . w . a . f technology does not require either user1 or user2 to install plug - ins or any other “ screen sharing ” technology on their respective client devices . four main s . w . a . f components may be added to the website 700 to enable user1 and user2 to co - browse / shop : a server - and - client s . w . a . f web - page components , 720 and 722 respectively , to index . php 710 ;

social graphs from a social - network , etc . the client - side s . w . a . f web - page components 722 may utilize javascript or jquery to perform at least the following functions : trigger off of elements in on the page index . php 710 , communicate a state - change of the elements to remote users , receive communications from remote users and change the state of local elements in index . php 710 . the communication between the client - side s . w . a . f web - page components 722 and the s . w . a . f server 724 , may utilize technology such as ajax . the s . w . a . f server 724 may communicate with the s . w . a . f database 726 . in various possible embodiments , the s . w . a . f server 724 and / or the s . w . a . f database 726 may be either internal to the website 700 , jointly or severally , and / or external ( e . g . hosted elsewhere on the internet ). fig8 is a generalized block diagram illustrating an ability to display suggestions to a user of connecting to other users who are shopping for similar items , via a s . w . a . f mechanism , in one possible embodiment of the present invention . a user browsing a website for one type of content , e . g . shopping for a type of items , may be privy to other information indicating other users , e . g . his / her friends , shopping for a similar type of item ; and may be offered a one - click s . w . a . f . connection to them to shop jointly . user8 400 , user2 802 a and user3 802 b , may be on one or more website &# 39 ; s that is part of a s . w . a . f system . these users may be at different geographic locations , accessing the website ( or websites ) from various different types of electronic devices and different web browsing applications . further , these users may be viewing different things on the websites ( s ). for example , one user may be shopping for a new cell phone , whereas another may be choosing a specific shoe in the right size . a system that is s . w . a . f - enabled is “ aware ” of the activities of each user via a s . w . a . f client engine that is active within a document displayed in the browser of each user , and which communicates with a s . w . a . f server engine . for example , users 802 a - 802 b may access a website via browsers 808 a - 808 b , respectively . the browsers 808 a - 808 b , may display web content that includes s . w . a . f client engines 806 a - 806 b , respectively , which may in turn , communicate with the s . w . a . f server engine 810 . similarly , user1 800 may browse a s . w . a . f enabled website whose content includes the s . w . a . f client engine 812 , also connected to the s . w . a . f server engine 810 . accordingly , one or more of the s . w . a . f client engines may present their corresponding users with information pertaining to other users &# 39 ; current browsing activities . for example , in the illustration of fig8 , user1 800 is shopping for an iphone . coincidentally , in the example , user3 802 b is also shopping for an iphone . accordingly , user1 800 may be notified of user3 &# 39 ; s activities , for example “ user32 is also shopping for iphone . would you like to shop together ?” 818 . in one presently - preferred embodiment , the connection may be facilitated with a single click on notification 818 , connecting to a live s . w . a . f session with users 3 . similarly , user3 may also be notified of user1 &# 39 ; s shopping for a similar type of item , and may be offered a one - click - connect . in one embodiment , the logic of presenting a user with notification of other users shopping for similar things , may take place in the user browser &# 39 ; s own s . w . a . f client engine . the s . w . a . f client engine is aware of what its own user is shopping for ; and receives information on other users &# 39 ; activities , and determines when to prompt its own local user of other users shopping for something similar . in another possible embodiment , a s . w . a . f server engine may monitor the activities of users connected thru it ; and may execute logic to send messages to users who are engaged in similar activities , offering them to join in a co - shopping experience . in another possible embodiment , a s . w . a . f client engine may actively send solicitation to other s . w . a . f client engines , querying them for their users &# 39 ; activities and displaying information and invitation to connect to users who are engaged in a similar activity . in various possible embodiments of the present invention , various privacy considerations may be implemented to control and limit users &# 39 ; view into other users activities . for example , but not limited to : allowing view only into activities of facebook friends and / or allowing a user to specify a global setting on whether their shopping activities may be viewed , and / or allowing a business to specify rules , and / or allowing users to select specific friends / stores / items which may be visible to others , etc . fig9 is a generalized block diagram illustrating a facebook ® application , operating in conjunction with a s . w . a . f system , in one embodiment of the present invention . a web - browsing application / browser 900 may display a url 902 ( uniform resource locator ) such as “ http :// apps . facebook . com / shopzebedo ”, which , in the example , is an application displaying an application canvass page 950 within the facebook ® framework . the application canvass page 950 may be a web - application external to facebook ®, presented in a frame within facebook ®, and connected to facebook ®&# 39 ; s social graph . in order to operate in conjunction with a s . wa . f system , the user &# 39 ; s browser 900 does not need to include any addition software such as plug - ins , activex controls , adobe flash ® player etc . a list of friends 904 a - 904 f may be presented to a user . the friends 904 a - 904 f may be facebook ® users who are friends of the current user , selected by various algorithms and sorted in various orders . for example , from left - to - right , friends 904 a - 904 c may be ordered in order of their birthdays — from soonest to latest ; or , alternatively , in order of their closeness to the user , etc . the friends 904 a - 904 c may also represent users who are actively online , i . e . actively logged into facebook ®. a list of users 904 d - 904 f may be comprised of users who are actively connected to the s . w . a . f system ( typically users using the website http :// apps . facebook . com / shopzebedo , although other websites may be connected with the same s . w . a . f system .) the users 904 d - 904 f may be available for immediate joint - shopping s . w . a . f session , given both their presence online and their existent connection to the underlying s . w . a . f system . the user may be prompted with a visual queue 906 to connect to any of the friends 904 a - 904 f . in the preferred embodiment , the visual queue 906 may be a popup that appears automatically when the user slides their cursor over one of the friends 904 a - 904 f . in the presently preferred embodiment , the user would “ single click ” on the visual queue 906 , associated with a friend 904 a - 904 f , and be automatically connected to that friend via a live s . w . a . f session . in the case of friends 904 d - 904 f , a direct s . w . a . f message may be sent from a s . w . a . f client engine component in the user &# 39 ; s browser 900 to corresponding s . w . a . f client engine component displayed in the friends &# 39 ; 904 a - 904 f browser , prompting the friend to accept or reject a live s . w . a . f session . in the case of friends 904 a - 904 c , given that they are not actively connected to the s . w . a . f system , as per fig6 , these friends may be presented with a facebook ® message ( e . g . on their wall , newsfeet , chat , etc .) asking them to navigate to the url 902 . once these friends navigate to that url ( and optionally accept additional terms / register ), they may be automatically connected to the s . w . a . f system ; and , may be automatically joined into a joint live s . w . a . f session with the user . selecting a facebook ® social plugin , such as “ share ” 924 , may allow the user to select a friend or friends , who may or may not be displayed as friends 904 a - 904 f , and for the selected friend ( s ) to be automatically connected to the present user via a live s . w . a . f session , once the selected friend ( s ) has / have navigated to the url 902 . a product 918 may be displayed for viewing and for purchase . the user may browse through available products using one or more graphical controls ; and , when in a live s . w . a . f session with one or more remote users , selecting a particular item 918 may cause that item to be selected for all connected users . similarly , the user &# 39 ; s clicking on any other control in the browser 900 may cause that control to be clicked in browsers of all remote users connected to the user via a live s . w . a . f session . similarly , the remote users &# 39 ; clicks on any controls in their browsers may cause a similar click to take place in the contents of the browser 900 . for example , one user &# 39 ; s clicking of the “ check out ” 920 button , beginning a checkout process ( possibly with a merchant in a separate browser from 900 ) may cause the same “ check out ” 920 button to be automatically selected in a remote user &# 39 ; s web browser , commencing the same purchase flow . similarly , selecting a media - playing button , such as “ play movie ” ( or “ pause ”, “ fast forward ”, etc .) 926 , may cause a movie ( e . g . off of youtube ®) to be played in the browser 900 — and also within the browser of a fiend in a live s . w . a . f session . it will be understood that the inventive system has been described with reference to particular embodiments , however additions , deletions and changes could be made to these embodiments without departing from the scope of the inventive system . although the order filling apparatus and method have been described include various components , it is well understood that these components and the described configuration can be modified and rearranged in various other configurations .
