Okay, that matches with my perception.

Yeah, but that beast has the additional advantage of being generally
useful and cool ;)

Hmmm... from the wiki description it reads like Skeleton may have a role
to play in this area...

"A player that decodes such a bitstream could then, for example, play
one video channel as the main video playback, alpha-blend another one on
top of it (e.g. a caption track), play a main Vorbis audio together with
several FLAC audio tracks simultaneously (e.g. as sound effects), and
provide a choice of Speex channels (e.g. providing commentary in
different languages)."

No, it's not stated that Skeleton does just that, but I guess it's
helping implementing that kind of stuff.

That sounds like a plan.

Thanks,
