[dev] topbarUpdate AJAX request

They do, though I have removed any dynamic updates that are prone to  
delay the topbar loading too much. Hermes' stop watches appear  
dynamically for example.
Another reason is a periodic ping to keep the session active.

No, it's basically what used to be the sidebar, and the menu items are  
provides by Horde_Registry_Application#topbar(), so they could change  
any time if the application sees fit.

I don't understand what you mean by that. Are you talking about  
partial menu tree updates?
