connecting to a dnode socket.io server from node

client.js

var io = require('socket.io-client');
var sock = io.connect('http://localhost:8080');
var dnode = require('dnode');

var Stream = require('stream');
var stream = new Stream;
stream.writable = true;
stream.readable = true;
stream.write = function (buf) {
    sock.emit('message', String(buf));
};
stream.destroy = stream.end = function () {
    sock.disconnect();
    stream.emit('end');
};

sock.on('message', function (msg) {
    stream.emit('data', msg);
});

sock.on('connect', function () {
    stream.emit('connect');
});

dnode.connect(stream, function (remote) {
    remote.cat(function (says) {

output
