A while ago (in the times of rc2) I was experimenting with 22.05 kHz
streams, and I remembered they worked. I was just a bit surprised that
they don't work with rc3, as they used to with rc2.
By "as they used to", I mean calling the same functions. It may be, that
underneath the API there is no managed bitrate in rc2, and this whole
thing in rc3 is brand new. But on the user / programmer side, I did call
managed bitrate functions in both cases, e.g. vorbis_encode_init(), and
not vorbis_encode_init_vbr(). Forgive me that I thought that this call
really does what it seems it does.
And it indeed does what it seems to do, in both rc2 and rc3. Calling
vorbis_encode_init() with appropriate bitrates does generate approx.
fixed bitrate output in both cases. I don't see how is this equivalent
to using vorbis in a non-managed manner, as the whole point for me is to
be able to specify the maximum bitrate, and this is what I have done.
I do understand that you say that VBR is much better, and that vorbis is
VBR inside. I hope you do understand my concerns as well, in particilar
the need to be able to produce low bitrate output.
Anyhow, all I'm looking for is a possibility to use ogg vorbis for
streaming to modem users with 33.6 kb/s modems. Any possibility (managed
bitrate or not, I don't care) would suit me fine. And this was my
original question, which was left unanswered. (Should I assume "no, I
can't" as an answer then?)

With all due respect, I think my inquiry did not warrant such a rude
