With oggenc, a sample line would be

oggenc --managed -b 30 -M 32 --resample 22050 input.wav

Your mails look to me as if you're only looking at this "two seconds
default window" and things like that, not practical tests... did you
actually run into trouble with what you were trying to do with Vorbis,
and if yes, what settings were you using? The example above might get
close to 31 kbps on rare occasions, and exceed 32 kbps for max. 2
seconds (much shorter, mostly) on uncommon music, if at all. A quick
test I made here never displayed more than 30 kbps in Winamp, with an
average bitrate of 29.9 kbps.

Also, Vorbis is a music/general purpose codec. You mention
videoconverencing and low latencies, wouldn't Speex be a lot more
interesting to look at? Why not pick the right tool for the job?
