title: webRTC multi-peer connection
body: <p>I have successfully connected clients A and B. Problem is I want to add new clients, C and D to build a group chat. 
  Do I need to spawn new RTC connection and exchange offer/answer/ICE candidates for each clients? For example:</p>
  
  <p>A connects to B
  A connects to C
  A connects to D
  B connects to C
  B connects to D
  C connects to D</p>
  
  <p>Each of the above client combination spawns their own RTCPeerConnection and goes through the webrtc handshake (offer,icecandidate,answer)</p>
