A *working* (on Windows) UDP Multicast client & server with Node.Js v0.10.25 (I spent a *LOT* of time getting EINVAL and I still don't quite know why :/)

client.js

var PORT = 5007 ;
var dgram = require('dgram');
var client = dgram.createSocket('udp4');

client.on('listening', function () {
  var address = client.address();
  console.log('UDP Client listening on ' + address.address + ":" + address.port);
  client.setBroadcast(true)
  client.setMulticastTTL(128); 
  client.addMembership('224.1.1.1');
});
  
client.on('message', function (message, remote) {   
  console.log('A: Epic Command Received. Preparing Relay.');
  console.log('B: From: ' + remote.address + ':' + remote.port +' - ' + message);
});
  
client.bind(PORT);

server.js

var news = [
  "Borussia Dortmund wins German championship",
  "Tornado warning for the Bay Area",
  "More rain for the weekend",
  "Android tablets take over the world",
  "iPad2 sold out",
  "Nation's rappers down to last two samples"
];

var dgram = require('dgram'); 
var server = dgram.createSocket("udp4"); 
server.bind( function() {
  server.setBroadcast(true)
  server.setMulticastTTL(128);
  setInterval(broadcastNew, 3000);
});
  
function broadcastNew() {
  var message = new Buffer(news[Math.floor(Math.random()*news.length)]);
  server.send(message, 0, message.length, 5007, "224.1.1.1");
  console.log("Sent " + message + " to the wire...");
}

By the way... why those weird messages?
