I'd like to move the gstreamer backend out of kdereview and into either 
kdemultimedia or kdebase for KDE 4.1.

After 4.1, I think phonon and its backends will have to release independently 
of KDE.

The GStreamer backend for 4.1 has an important difference to the one in Qt4.4: 
It integrates correctly into the device preference settings - just like the 
phonon xine backend does already.

I don't want to move any of the other backends as I don't work on those and 
can't test them. As I don't know of any KDE people working on them or anybody 
interested in getting them into a KDE 4.1 release I see no point in moving 
them to a KDE module. They just need some open repository until Phonon has 
found its right place.
