title: audio conference with WebRTC
body: <p>i would like build an only-audio conference system based on webrtc for a game, but i must avoid lag.<br>
  for example i can use <a href="https://github.com/muaz-khan/WebRTC-Experiment/tree/master/RTCMultiConnection" rel="nofollow">https://github.com/muaz-khan/WebRTC-Experiment/tree/master/RTCMultiConnection</a><br>
  How many clients can be connected in the same time?and about bandwidth?<br>
  I think that the upload will be a limit increasing the amount of connected client.<br>
  Could i make a Tree of clients, so each client have only 2 or 3 connections?  </p>
  
  <p>The server can be in any language because i will use vert.x<br>
  regards</p>
