[webkit-dev] New feature announcement – Video conferencing and peer-to-peer communication

[Tommy Widenflycht (ᛏᚮᛘᛘᚤ)]

The plan is to have the P2P VC WebKit code to do as little as possible
and leave the implementation to the browser port, just like the
MediaStream patches. And the code touches very little other code;
Event, EventTarget, Navigator etc but obviously heavily depends on the
MediaStream functionality.

Is this a problem? Happy to modularize the functionality if someone
can give me some pointers, show our work in progress etc.

To get the standard (on whatwg) finalized an implementation is needed
so that some real world usage can be had, and previously we have
received some favorable comments re go-ahead on implementation.

Personally I think this is a great feature and are committed  to
implement it properly.
