There is no use case. WebSocket is NOT designed for carrying media.

WebSocket is designed for sending and receiving *boundary* messages
(with any application content up to the developer) over an existing
TCP connection between client and server, in both directions. When a
WebSocket message arrives to the browser, a JavaScript callback
onmessage(data) is called, so the custom JavaScript code can read it,
parse it and react according.

This stuff is NOT designed for media !

Please read:

http://tools.ietf.org/html/draft-ietf-hybi-thewebsocketprotocol-17
http://dev.w3.org/html5/websockets/#the-websocket-interface


I strongly hope this WG will not waste time in discussions about "RTP
over WebSocket", or it will become surrealist.

Regards.
