Russell -
I'm really glad to hear this. Ogg Vorbis is definitely a quality
approach and (unlike much media work) shares our commitment to open
source.
Good for you to have kept it pure. A while ago we had a sort of
competition to see how much could be squeezed out of a naive
implementation of Tetris. As I recall it was a factor of two in
space and considerably more in speed. I haven't looked at your code
yet, but maybe this would make another good exercise for the
over-brained and under-employed denizens of this list.
And yes; once it has been cleaned up and tested, plugins will do
wonders for the speed, though my enthusiasm lies more with JITs right
now (actually since the beginning * ;-).
Thanks for the hard work and the implicit challenge!

(*) if it's written for slang, even a modest JIT ought to do well
with it, right?
