I doubt there's a unique IP address per phone on a carrier data network -- it feels like too many addresses would be needed. It's probably NATted or the equivalent. Hence, I'm not convinced a phone can serve as a server (TCP or UDP) without help, a la P2P NAT-traversal systems. But, then again, I've certainly been wrong before... -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 1.4 Published! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
