Sockets and socket.io

I use socket.io to enable browser to browser communication in a number of projects.

For example, a client running in Chrome might include:

	var socket = io();
	socket.on('matrix', function(packet) {
		// Process packet
	});
    socket.emit('register',{'artworkid': artworkid, 'artworktype': artworktype});

And on the node.js server. This would "bounce" the messages between clients:

io.on('connection', function(socket) {
  console.log('Connected');
  socket.on('disconnect', function() {
    console.log('Disconnected');
	console.log("Clients: "+Object.keys(io.sockets.clients));
  });

  socket.on('register', function(msg) {
  	socket.artworkid = msg.artworkid;
  	socket.artworktype = msg.artworktype;
  	console.log("Registered: "+msg.artworkid+" "+msg.artworktype);
  });

  socket.on('matrix', function(msg) {
  	socket.broadcast.emit("matrix", msg);
    //console.log("matrix: "+msg);
  });
});

How do I get a client running on the Espruino to join in? I don't think there is a socket.io library for Espruino so do I need to use ordinary sockets to do the same job? Would I need to take messages received in socket.io and resend them to the Esprunio and visa versa? Are there some good examples of Espruino to node.js communication via sockets that I should be looking at?

Thanks,
