Will the token tables be transported as frequency histograms as is
done in the current source? That means:
80 tables * 32 freqs/table * 2 bytes/freq = 5120 bytes
Okay, I guess I see where you're coming from. If someone were to try to
encapsulate this data in an AVI, ASF, or MOV file (just in case Ogg
adoption doesn't take off right away), I guess it would need to go inside
the video header?

But there is still the minor issue of compatibility with VP3
streams which necessitates the inclusion of the classic tables.
