title: node.js, XMPP Strophe.js
body: <p>I am currently thinking of adding a realtime notification system to my site and so far my choices are using node.js or an XMPP server with a js XMPP librairy such as strophe.js. 
  Right now i will just need it for a realtime notification systems on my site, but it will likely evole in more complexe features such as a chat system.</p>
  
  <p>So i have the following questions:  </p>
  
  <ol>
  <li><p>How do these 2 technologies differs ?</p></li>
  <li><p>Which of these 2 technologies would be "more suitable" to integrate in a site running on a LAMP environement.</p></li>
  </ol>
  
  <p>Thanks,</p>
