UDP is a whole different ball game. It's lossy, it doesn't traverse 
through NATs, it has size limitations -- all of these things mean that the 
current WebSocket handshake and protocol simply wouldn't work with it.

If you adjust it to work, then you end up with what the spec has, which is 
the UDP data stream component of PeerConnection.
