Well, I thought of some timed-based process that would inquery about "server" status and thus show messages.

If you think of how ExtJS-based modules are done, the idea is to provide a framework for extensions with toolbar and the rest, meaning the extension should not have to worry about how flash message 
are rendered, this is done by the ExtJS framework. If you want AJAX to push messages to DOM, then it implies that the ExtJS framework should provide an API for making AJAX request, intercept such 
flash messages and then clean-up the response and send it back to the originator module. That sounds a bit complicated to implement, if "possible" at all.
