What about: all .mcopclass files are stored in

$KDEDIR/lib/mcopclass ?

One directory where the .mcopclass files are stored.
xmms has fixed directories too, where the plugins should
go.(input/output,..)

The thing with recusive scanning is even worse on Mandrake 7.2.
In fact kaiman (or artsbuilder, which I found out later) 
never would start in Mandrake 7.2 because 
they have "backreferences" in /usr/lib.

In /usr/lib/mecury they have int2s -> ../mercury
and this leads to an endlees loop in the scanning.

Hm, if the only application which scans for .mcopfiles is
artsd itsself then we have no problem with this!
             
If we define a common directory where the .mcopfiles go,
we need to fix arts and artspluggy maybe artsbuilder
and that should be all.
(simple change in Makefile.am.)

Maybe I forgot something?
