title: Need multiple iPads to communicate with each other
body: <p>We are building an iPad App for an enterprise scenario.   Users will be using the iPads to check in guests at special corporate events.   There could be as many as a dozen iPads used for check-ins and they all need to have accurate data on who has been checked in, when and any notes that have been entered.  The catch is that there will often be no internet access.   So the iPads must be able to communicate with each other.   All iPads will be at one location, but they could be as far as 100-300 feet apart.   I suppose we can include a requirement that users need to periodically move close to each other if the distance is too far.</p>
  
  <p>We are open to either a peer-to-peer solution where by the iPads actually talk to each other, or we can have a central laptop which acts as a server and the iPads all talk to the server.   Any thoughts on how this can be done, what the options are, if we need to establish a wifi network, etc., etc.</p>
  
  <p>Thanks in advance.</p>
