Could I suggest yet another oggenc option -- multiplexing several
uncompressed audio files into one Vorbis stream (i.e. channel 1 and 2
from left and right of file1.wav, channel 3 and 4 from left and right
of file2.wav, etc.)?

So when transcoding ac3 -> Vorbis, you could somehow convince the
decoder to give you a bunch of regular stereo (or even mono) output
files, for front left, right, rear left, right, center, sub, and
whatever else they've thrown in these days, and just pull them all
together during the encode.

Coupling is a different story. What exactly will the current channel
coupling do on (a) more than 2 channels and (b) two channels that have
nothing to do with each other (like producer commentary, alternate
language, etc. tracks available on many DVDs)?
