Vorbis dev - Mar 2006 - Split an audio in more part (not time based) and recreate the original

Hi all,
I would like to split an audio stream into more encoded flows (for 
example 1, 2 and 3). This division isn't time based (Maybe frequency 
based).
The substreams that have these features:
1)  The flows  must be re-assemblable and must generate the original 
stream (1+2+3 = original stream)
2)  I can listen only the flow number 1 (even if the audio quality is 
worst than the original, of course)
3)  I can listen only the flows number 1 and 2 (the quality of the audio 
is better than if I've got only the flow number 1, but worst than if 
I've got all the three flows)
4) Each flow use less bandwidth than the original flow (otherwise is 
useless!)

It is like TV that broadcast black&white information and colours. We can 
view only B&W , or we can view also the colors.

Vorbis can help me to do this? How hard is it?

It is possible, but you need to be familiar with the vorbis specification, and 
be able to code adequately in some programming language.

What kills me, doesn't make me stronger.

Ok, but what is the helpVorbis can give to me? It can help me only to 
encode and syncronize the bitstreams or also to mux some concurrent 
audio stream (of the same audio channel)  and give me result stream? Can 
you suggest me something specific for start this study?

Thank you,
