Hi,
I can't speak for the xiph people, since I'm not an official developer,
but I think I can answer a few of your questions.

It's all not that difficult. I'm currently in my first year of CS at the
University of Twente, and although I haven't yet the knowledge to
understand the details of vorbis, I'm sure that I could if I wouldn't
rather spend my time investigating video codecs. Besides, wavelets were
invented by a physicist :)

Looks nice, although I think that the current very-beta Tarkin sources
do more or less the same. They use a 3D wavelet transform, which is
probably better than differential encoding in the time domain. You can
grab the current rather crude IMHO Tarkin code here:

Well, I think Vorbis comes with a TODO list, and so does that Tarkin
source. I've been doing some wavelet stuff but atm my time is rather
limited. I suppose doing documentation is always welcome, but I think
someone else needs to say something about that.
Cheers,
Lourens

Don't think so, but Tarkin-dev discussion is welcome here.
