[jdev] ANN: strophe.jingle -- a jingle/webrtc plugin for strophe

[Philipp Hancke]

mattj thinks this ought to be announced here, too. Announcement text is 
mostly courtesy of ralphm :-)

strophe.jingle is a webrtc connection plugin for strophe.js. Strophe is a 
popular library for writing XMPP client applications that run on any of 
the current popular browsers. Instead of the native TCP binding, 
strophe.js uses BOSH (Bidirectional-streams Over Synchronous HTTP, a 
variant of long polling) to connect to an XMPP server. Besides enabling 
anyone to build (federated) IM applications, this opens up the browser as 
an addressable endpoint for two-way exchange of structured messages, 
including presence and publish-subscribe applications.

This plugin makes it possible to negotiate audio/video streams via XMPP 
and then relinquish control to the WebRTC support of browsers like Firefox 
and Chrome for the actual out-of-band media streams. With XMPP/Jingle you 
get the authenticated, secured and federated media signaling, whereas 
WebRTC gives you an API to set up the media streams using RTP/ICE/STUN and 
provide access to cameras and microphones.
Features:
- mostly standards-compliant jingle, mapping from WebRTCs SDP to Jingle
   and vice versa. Aiming for full compliance.
- tested with chrome and firefox.
- trickle and non-trickle modes for ICE (XEP-0176). Even supports early
   candidates from peer using PRANSWER.
- support for fetching time-limited STUN/TURN credentials through
   XEP-0215. rfc5766-turn-server is a TURN server which implements this method.
   a sample demonstrating the use of this to build a federated multi-user
   conference (in full-mesh mode).

Thanks to my employer for the permission to release this under MIT
