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.
How hard would it be to add this final layer of abstraction to Ogg
(in a backwards-compatible fashion of course)?
 Modulo any bugs in QuickTime like the ones in QuickTime 6 that
caused some problems for the Ogg Vorbis CODEC of course.
