CODECs (going off-topic)

D-Bus is being used in a lot of places to replace Bonobo.  See, Bonobo was originally meant to
be far more than just an embedding technology (it was a compound document format,
inter-application communication framework, etc etc).  D-Bus is just meant to replace the IAC.

Bonobo isn't deprecated yet.  It's still used for embedding and a few other legacy places.
Its days are numbered, yes, but the number is still pretty high.  :)  The Gnome project seems
to be moving methodically, replacing Bonobo one piece at a time.  Personally, I don't think
that's a bad strategy.
