a system and related techniques prepare and condition the installation of new networked service or application components , such as internet services , based on an individual subscriber &# 39 ; s subscribed - to services , features and other components . a subscriber to an internet service may choose to add , for example , a componentized subscription to a music or video download service to their access plan . when the user inserts a cdrom or accesses a web site for installation , the user may be prompted for a username or passport - type object to authenticate their account . the user may then be presented with a set of available service selections , extensions or enhancements to choose to add to their plan . those available selections may be prefiltered or prequalified , for example , based on geographic location , account spending or access limits , language or other criteria . because the installation engine delivers components which are intelligently filtered at time of installation , the service components or applications can be tailored to that specific user &# 39 ; s needs and options , instead of downloading or installing a monolithic package which may contain services not available or of interest to that user .
