You think that because your idea of the notification deamon is not the same 
that KNotify.

From what i see, you just want a deamon to popup messages to the user. KNotify 
is not that  (but can do that)

KNotify handle all KDE events. That include for example KWin event when a 
window is maximized. KNotify will read the config file, and see if the user 
want to play a sound, and which one.  Of course, it is stupid to show a 
passive popup for such as events.

There are severals advantage of having "KNotify" handle itself the config 
1) Less code duplication over the application, and applicaiton are shorter to 
2) The Notify configuration UI is exactly the same for every application
3) We can apply sounds themes easily that may include all applicaiton (exactly 
like for icon themes)

Historicaly, KNotify was first only for sounds, and after, it has been 
completed to do much more things.

If we assume the configuration is hanlded client-side. The client has to tell 
the server somehow what it want to be performed.
