OK, sounds like we're all back to reason.  

To verify the spec, what we really need is an experienced programmer
without deep internal knowledge of vorbis (at least, one who can't
quote large swatchs of the libvorbis code from memory).  This will not
only give a great practical critique of the code, but also proveide
the fully 'genetically-independent' implementation many standards
bodies require.  The current Vorbis code was written for ease of
maintainence.  A from-scratch implementation could focus on some other
goal as well, such as lower resource use.  

That's a big enough project to warrant a slashdotting when it's finished.

Note that I *did* code quite a few tests directly from the spec, but
several of the bugs that have come up from the spec were due to me
being too familiar with the pieces and duplicating correct code from
memory without realizing it.
