Presently, each application is choosing how/where to show notifications 
manually. They should be able to use QSystemTrayIcon::showMessage() and 
have the system tray do it, but it's unsupported (on the system tray 
side). Are "notifications" basically an implementation of this feature?

I've written the code to accept "balloon messages" for the FDO spec, but 
there's currently no code to actually display them. It seems that the 
notifications display code could be reused for this? It also seems like 
a good idea to separate the notion of a tray icon and an application 
message as far as the systray/core stuff goes...
