We want to create an application (possibly 2) that will enable an iPad to act as a "base station" and other devices (iPod touch or iPhone) to be "call stations".
It needs to mimic a typical video intercom.
All only needs to work over WiFi.
We are developing additional hardware for the iPod devices to access the serial I/O.
Please see detailed specification and feel free to comment and also let me know if this can be acheived.
