title: Communicating directly between two mobile devices
body: <p>I'm mostly interested in a general answer for mobile, but something android specific would be acceptable.</p>
  
  <p>Given 2 mobile devices, how can I get a connection between them. I'm new to mobile development, and I'm not sure what kind of NAT mobile devices are behind. Is it possible to do some sort of "hole punching"(using an outside server to aid in getting a connection) to connect them together?</p>
  
  <p>I've looked at this question, but it didn't help me too much, I still don't know how to get an IP and/or traverse a NAT.
