title: Random.UUID in WebRTC Signaling
body: <p>I've read threw a couple examples of setting up video chat on android using WebRTC. </p>
  
  <p>During the signaling processes, I've <code>UUID.randomUUID()</code>, to generate a unique id for the users involved in the burgeoning connection. </p>
  
  <p>I am using Firebase to authenticate users. Is it possible to the UID generated by <code>Firebase Auth</code> as the unique id or is there a reason I should use <code>UUID.randomUUID()</code> specifically?</p>
