In a nutshell:

WebRTC is a combined effort between IETF and W3C to bring realtime 
communications to web browsers. WebRTC only specifies the media plane, so 
signaling is up to applications. Here is the draft specifying the WebSocket 
transport for SIP: 
http://tools.ietf.org/html/draft-ietf-sipcore-sip-websocket-05 which allows 
applications written in JavaScript and running in web browsers to connect to 
existing SIP infrastructure.

Since OpenSIPS is a SIP proxy and thus is not concerned by the media plane, 
supporting the WebSocket transport is what would be required for it to enter 
the "WebRTC game". That said, IMHIO, makes little to no sense to do it until 
TCP works properly, given that WebSocket is a transport protocol on top of TCP.
