title: implementing a chat webapplication
body: <p>I need to develop a web application with a chat feature, and I would like to know if there are any sophisticated ways to create a realtime web-application with a push engine.</p>
  
  <p>I know jQuery, and I can handle to create a chat web-application which, in the client side, check every period for new messages, and show them, but I don't like this solution and I was wondering if there are any better ways to do it.</p>
  
  <p>In my research I discovered the existence <a href="http://www.ape-project.org/" rel="nofollow">Ajax Push Engine</a> project, and it looks like what I need, but when I was navigating in their website I found it not very well done and somehow incomplete, so I was wondring if there API is stable enough to be put in a production environment if not are there any other solutions?</p>
  
  <p>Sorry if I made it long, any <strong>help/hint/link/suggestion</strong> would be very welcomed :) </p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I would like to specify that I'm working with PHP in the server side</p>
