Vorbis - Mar 2001 - Ogg/Vorbis Downsampling?

Dear Vorbis Gurus to whom I owe a debt of gratitude for creating such a
kick-ass audio encoding scheme:

I'm probably using the wrong term of "downsampling" here, but here
goes.

I remember reading about Vorbis being designed with streaming in mind. I
was wondering if one aspect was to allow easy ad-hoc downsampling (e.g.
going from 192kb/s to 128kb/s) without re-encoding. Does such a facility
exist in the Ogg format or Vorbis encoding?

Regards,

Downsampling is indeed very much the wrong term here :)
This is what we call 'bitrate peeling'. The vorbis format is designed
to be able to do this, but there aren't any tools for doing it yet.
If one wanted, and the code gets written (which is probably will, 
eventually), a streaming server could dynamically adjust each stream
to the available bitrate using this.
