Data Channel Example
View datachannels.js
* Assume we've connected a PeerConnection with a friend - usually with audio
* and/or video. For the time being, always at least include a 'fake' audio
* stream - this will be fixed soon.
* connectDataConnection is a temporary function that will soon disappear.
* The two sides need to use inverted copies of the two numbers (eg. 5000, 5001
* on one side, 5001, 5000 on the other)
pc.connectDataConnection(5001, 5000);
