The QuickTime movie format is also intended as a container format and 
is also very easy to pick up and use for new purposes.

And many of these "new" purposes aren't "new" - if you add a Speex 
CODEC to QuickTime, you can add a Speex track media to any audio 
track.  Nobody else's code has to know about Speex, it just works.[1]

How hard would it be to add this final layer of abstraction to Ogg 
(in a backwards-compatible fashion of course)?

[1] Modulo any bugs in QuickTime like the ones in QuickTime 6 that 
caused some problems for the Ogg Vorbis CODEC of course.
