signaling for RTCMultiConnection-v1.4 and earlier releases

var SIGNALING_SERVER = 'http://domain.com:8888/';
connection.openSignalingChannel = function(config) {   
   var channel = config.channel || this.channel || 'one-to-one-video-chat';
   var sender = Math.round(Math.random() * 60535) + 5000;
   
   io.connect(SIGNALING_SERVER).emit('new-channel', {
      channel: channel,
      sender : sender
   });
   
   var socket = io.connect(SIGNALING_SERVER + channel);
   socket.channel = channel;
   
   socket.on('connect', function () {
      if (config.callback) config.callback(socket);
   });
   
   socket.send = function (message) {
        socket.emit('message', {
            sender: sender,
            data  : message
        });
    };
   
   socket.on('message', config.onmessage);
};

signaling using socket.io over node.js

Signaling for all latest experiments and newer releases.

Your server-side node.js code looks like this:

io.sockets.on('connection', function (socket) {
    socket.on('message', function (data) {
        socket.broadcast.emit('message', data);
    });
});

And to override openSignalingChannel on the client side:

connection.openSignalingChannel = function(callback) {
    return io.connect().on('message', callback);
};
