Is this how MT9 does it? I considered this but thought there might be a
better way since wouldn't this take up a lot more space?

Technically, I have no idea.
It could be possible to encode deltas for similar tracks (same as for doing,
eg, stereo recordings), but I'm not sure if you'd get anything better
for
different instruments as the tracks would be wildly different in the first
place.
Still, it would be nice to see Vorbis players handling time multiplexed
streams, just for the fun of it :)

Hm, well is there a way to label the different tracks in an ogg file right
now? That way they could be labeled with "Lead Vocal" "Lead
Guitar" etc.

I've filed a bug report on launchpad but wasn't sure that i understood
it
all correctly and worded it right-- please add to it as you see fit
