There is more than one way to appraoch the problem.  

One approach seeks to implement a peeler that will work on any stream.
I think this approach is perfectly possible.  However...

Approach B relies on the encoder pre-structuring a stream to be easy
to peel.  I think this approach is simpler/faster to implement in the
decoder/splitter, and will result in higher final quality.  It will
require a more complex encoder.
