Vorbis - May 2005 - Bitrate peeling on existing (older) streams ?

Hi all,

last time I have seen discussions here about alternative encoders, or
tuned versions of the encoder.
Last year (sept/oct) there had been the discussion if existing streams
will be peelable or if they have to be "modified" first to be
peelable.

Now for my question:

Is it known allready if existing streams will be peelable or not ?
Or, with other words: Is it known if the /can/ be modified in a way
that they are peelable ? If so, will the stream loose in quality
when doing such modification ?
Which of the existing encoders one should use to get streams which
will be peelable in future ?
I think I am not alone with this questions, since it is one of the
most elementar advantages over other lossless encoded formats (like
mp3) - I dont bother if it will take some more years to /implement/
peeling, but I really would bother if when its done, I should realise
that none of my streams actually is peelable (and possibly cant made
peelable ?)

Thanks in advance for any hints,

Dominic Radermacher

That's probably just a typo, but to be clear (because this is important...):

MP3 and Vorbis (among others) are *lossy* audio codecs.
FLAC, Shorten and Monkey's Audio (among others) are lossless.

A lossless codec would always be "peelable", because it contains all
the
original information of the unencoded audio stream.  (The only question
would be how efficient the "peeling" process could be made.)
