Let me throw in my $0.02 as well -- I have designed a threaded Ogg encoder
(see http://www.mpi.nd.edu/~jsquyres/vorbis/) that would use multiple
threads to encode a single song (slightly different than the above
description).

But I haven't implemented it yet because last I checked, the library was
*not* thread safe, and Bad Things happened when I wrote up a trivial
multi-threaded encoder.  Last I heard, making it thread safe was "on the
list".  Has any progress been made in this area?
