ICE inherently does not support 1:many, but yes you use ICE for each 
peer to establish a unique PeerConnection with every other peer.

There's no reason that the PeerConnection object has to map the 
underlying ICE negotiation exactly, but even if it does, our 
PeerConnection factory proposal (PeerListener) allows for a web 
developer to express his intent to create multiple PeerConnection 
objects. In other words, it makes it easier for the developer to 
establish a 1:many stream without having to create each PeerConnection
