Still, only one player actually uses it (Audacious).  There are rumours Amarok 2 will support it.  VLC 0.9.0 should support it.

Do I understand the code correct that in order to be detected, one has
to register itself as org. mpris.SomePlayer? I would expect kde apps
registering themselves as org.kde.SomePlayer and having some object
supporting the org. mpris.Xxx interfaces, no?

KMPlayer inherits from it. In Kde3 it was requited for mm kparts to
implement this so it could be use as previewer in the file dialog. Got
a nice dcop interface for free.
Don't know if this is still true, didn't get a nice dbus object from
it ... there is a .xml file, but not added to the build unfortunately.

Do get a dbus object from phonon 'AudioOutputs', no info about current
stream afaics.
