Here is the app.js for the demo i'm trying to upload to nodejitso

// Including libraries

var app = require('express').createServer(handler),
    io = require('socket.io').listen(app),
    static = require('node-static'); // for serving files
var path = require("path");
// This will make all the files in the current folder
// accessible from the web
var fileServer = new static.Server('/');

// usernames which are currently connected to the chat
var usernames = {};

// This is the port for our web server.
// you will need to go to http://localhost:8080 to see it
app.listen(80);

// If the URL of the socket server is opened in a browser
function handler (request, response) {

    request.addListener('end', function () {
        fileServer.serve(request, response); // this will return the correct file
    });
}

// Delete this row if you want to see debug messages
io.set('log level', 1);

// Listen for incoming connections from clients
io.sockets.on('connection', function (socket) {

    // Start listening for mouse move events
    socket.on('mousemove', function (data) {

        // This line sends the event (broadcasts it)
        // to everyone except the originating client.
        socket.broadcast.emit('moving', data);
    });

    socket.on('sendchat', function (data) {
  	// we tell the client to execute 'updatechat' with 2 parameters
		io.sockets.emit('updatechat', socket.username, data);
	});

	socket.on('adduser', function(username){
		// we store the username in the socket session for this client
		socket.username = username;
		// add the client's username to the global list
		usernames[username] = username;
		// echo to client they've connected
		socket.emit('updatechat', 'SERVER', 'you have connected');
		// echo globally (all clients) that a person has connected
		socket.broadcast.emit('updatechat', 'SERVER', username + ' has connected');
		// update the list of users in chat, client-side
		io.sockets.emit('updateusers', usernames);
	});

});
