The only reason it would not work on 3G, that I can think of, is that the carrier might block connections to specific ports on outgoing. However, I don't think this is strictly point to point. If you have 2 iPad talking to each other they are both behind NAT then they both must connect to a server outside their NATs that will act as a sort of proxy.
