I've read this a number of times and it finally occurred to me to ask for
clarification.  I think i understand "no tools yet" as far as the server doing
the streaming goes but does a vorbis encoded stream (lack of tools aside)
currently implement this concept so that, were the tool available, the stream
could be peeled down to a lower bit rate?  I'm guessing the answer is yes, but
"format is designed to be able to do this" sounds a little ambivalent on the
matter.  Is this because it _should_ work but simply hasn't been tested yet?
