[vorbis] bitrate peeling question

[Henry Rearden]

hi all,

i have two questions about bitrate peeling that i hope someone
on this list can answer:

1) my understanding is that BP allows you to derive a lower-
bitrate version of an encoded file (say 128kbps) directly from
a higher-bitrate version (say 192kbps), without having to re-rip
from a CD or generate an intermediate WAV file.

this is potentially a huge win for those who want to archive all
their CDs into high-quality Oggs, and to then use files from that
same archive on their Ogg-capable portable players (don't i wish)
when going to exercise, etc. is my understanding of how BP is
supposed to work correct, or am i missing something?

2) is BP currently implemented? if so, how do i use it? if not,
any idea as to when it will be working?

thanks.
