Tuning the CDMA radio and sending and receiving data might be rather difficult unless someone reprogrammed the DSP and I've never heard of that being accomplished on any phone. If it was then it would be rather bad for everybody to have rogue transceivers on the spectrum talking to eachother rather than registering with the tower. =)
I liked the WiFi idea... What if an app used a specific SSID, AD-HOC mode, and broadcasted its presence at a regular interval. Other phones running the app could listen for those broadcasts and register the nearby users in a list. Then users could select someone from the list to talk (VOIP) or transfer data... The service could run in the background listening for nearby hosts, registering with them (alert user of their proximity?).
Just thinking out loud.
