title: Instant Messaging on Android with Google Cloud Messaging
body: <p>I was just looking at the new Google Cloud Messaging (GCM) and I was wondering if it is possible to use GCM for Instant Messaging on your Android application?</p>
  
  <p>I saw you can send data, like a message, from a server, but is it also possible to send from one device to another one?
  And how would this work?
  Some example code would be really helpful..</p>
  
  <p>Tnx!</p>
