Unix domain sockets allow you to pass file descriptors between
processes.  It might be interesting to pass a WebSocket endpoint
across a WebSocket.  If the clients can punch through NATs, it becomes
a direct peer-to-peer connection, otherwise it gets proxied through
the server.  Probably makes implementations excessively complicated,
though.  UDP-style would be easier (no need to worry about data
received by the server after it initiates pushing the endpoint to the
other client - just drop it on the floor).
