 # What browsers it is supported in.

 I think we want to use reliable (TCP) "RTCDataChannels"; their API is
 extremely similar to WebSockets.  The support for this part of the WebRTC
 spec is still very new; most people are using the audio/video UDP APIs
 instead.

 Chrome only supports RTCDataChannels using RDP (which is UDP plus headers)
 at the moment.  Firefox *does* support reliable RTCDataChannels in Firefox
 Nightly, behind a flag.  Firefox and Chrome RTCDataChannels aren't
 interoperable, but that's okay for us because the Flashproxy design never
 has one browser's socket talking to another browser's socket.

 So I think the short answer is that we could start implementing in Firefox
 now, with the expectation that one day the same code will work in Chrome.
