I'm pretty sure the fundamental AJAX pattern is that you send  
XMLHttpRequests on some event, either a timer (so it polls) or a user  
action (e.g. an on-click handler). I've never seen the pattern of a  
persistent connection ... if you have that, you may as well just write a  
traditional socket client/server application and deal with scalability  
there. :)
