Yep, the notification system and OSD have really different purposes. OSD should only
provide feedback against an action triggered by the user (especially through some input methods)
but notifications are generally for notifying users about what's going on the overall system right now,
e.g. file copying status, disc burning status, kopete message, etc.

OSD should really be simple, sleek, short-duration widget which doesn't accept any other input
once drawed on the screen like through push buttons, etc.

A D-Bus service for rendering plasma-themed, custom-positioned/transparency OSD should be enough
for KDE applications.

That's what KOSD is doing: It owns org.kde.kosd and offers a generic showCustom() method and other
specialized methods like showBrightness(), showVolume(), etc. I don't think It is still maintained,
it has just one release until now.

I'll try to share my experiences with KOSD, KMix and battery-applet altogether with the patch in $subject
as I'm planning to do the integration for the upcoming Pardus 2009.2.
