How to establish p2p connection between two phones?
<p>I just want to write an app for andorid which is very similar to facetime on iphone or skype's video. Just want to implement a P2P connection for video transmit and display. Is there somebody who has some related document or code about that. And one thing I want to know is how to establish a p2p connection between two phones? Just need the IP address to establish a tcp connection or I need some other information. And also if two phone are not in the same LAN or have firewall between them, how could I do it?</p>

<p>Thanks!</p>
