title: Android Phone-to-Phone Communications
body: <p>This is more about an explanation then it is about asking a question. What I am wondering is if its possible to write an Android application that can communicate with another Android phone, given the phone number of the phone I want to communicate with. By communicate, I mean I want to be able to send data to the phone and have my application on the other phone be able to recive it.</p>
  
  <p>If its not possible to do this, then I guess my alternative is to have my application "sign" the phone into a server. Then I'm assuming the server can act a proxy to communicate with both phones. </p>
  
  <p>Any clarification would be helpful!</p>
