I took your example and dropped it in an a node app using express. Your HTML code was placed in a static HTML file under public. Your example worked fine. The code is shown below. I wanted to make sure both the socket.io script file and the HTML file were being served up properly.

var http = require('http'),  
    io = require('socket.io'),
    express = require('express');

var app = module.exports = express.createServer();

// Configuration

app.configure(function(){
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

if (!module.parent) {
  app.listen(9000);
  console.log("server started at %s", (new Date()).toUTCString());
  console.log("listening on port %d", app.address().port);
}


// socket.io 
var socket = io.listen(app); 
socket.on('connection', function(client){ 
    console.log("New client is here!");
    client.send("hello world");
    client.on('message', function(msg){ console.log("client has sent:"+msg); }) ;
    client.on('disconnect', function(){ console.log("Client has disconnected"); }) ;
    client.on('disconnect', function(){ }) 
 });
