Yes, I realized that, despite killing the joke. =)  However...

This is incorrect.  I am in fact serious about my analysis.  It seems
bitpeeling isn't so trivial or, at least, not so obvious.  I always
imagined that bitpeeling would be like removing the higher-order terms
of a Taylor series: the resulting function typically just starts to
look less like the limit, but doesn't go whacked all over the place.

Is there a document in which I can read about the mathematics behind
Vorbis?  I'd like to take a look at this bitpeeling, especially since
it's been vaporware for at least 2 years, and I'd like to have it. =)

Cheers,
Kyle
