This could be done, assuming that one has the "peeled" bits as well.

To see something conceptually similar (although probably completely 
different in reality), check out WavPack (http://www.wavpack.com/).  It's a 
lossless codec with a "hybrid" mode, where a lossy file + recovery file are 
created.

It's an interesting thing, but I've never been able to contrive a situation 
where it's useful _for me_.  Vorbis's peeling abilities, OTOH, have very 
obvious uses for streaming.
