mmmm, i don't really get what you're looking for but socket-programming with node.js (and socket.io) is really straight forward. take a look at some examples on the socket.io homepage:

// note, io.listen() will create a http server for you
var io = require('socket.io').listen(80);

io.sockets.on('connection', function (socket) {
  io.sockets.emit('this', { will: 'be received by everyone connected'});

  socket.on('private message', function (from, msg) {
    console.log('I received a private message by ', from, ' saying ', msg);
  });

  socket.on('disconnect', function () {
    sockets.emit('user disconnected');
  });
});

on connecting to the server, every socket get an unique id with which you can identify it later on.

hope this helps!? cheers
