I'm using announcements so I'll try this. Thanks for the lead.

You are probably like to have a Comet, or so called Reverse Ajax instant 
  updating of an element of your web page when some event occurs?

In Aida this is easy achievable by deferring a response to periodic Ajax 
update of that element until an event occurs. And to signal that event, 
you can use Vasily's Announcements, a very very useful thing in general!
