I committed an initial working plugin here which needs heavy reviewing:
http://websvn.kde.org/trunk/playground/base/kded_kosd/knotify-osd/

Initial commit log message contains an abstract on what I have done and what needs to be done:

"""
Currently there's no way to pass some extra information over knotification so
the progress information is unknown to the plugin.

The D-Bus handling stuff is copied from notifybypopup and is not tested yet.

update() logic isn't also tested. I don't know what the logic there should be
in order to update the available OSD.

The OSD is a Plasma::Dialog with a basic QGridLayout inside. I tried hard to use
Plasma::Meter instead of QProgressBar but I failed as it needs switching
the whole UI elements with their QGraphicsxx counterparts.

Beside all of this, you can write down a kmix.notifyrc with Action=Osd, patch it to call
KNotification::event with appropriate icons and everything will work as expected.

Any help will be really appreciated.
