     I like your design, it seems to strike a good balance between 
elegance and practicality. The only thing missing for the latter is a 
deeper support for chunking. Of course, that would probably destroy some 
of the elegance [1]. I don't think that problem has been solved in any 
of the enumerator/iteratee/pipe/wire/conduit libraries so far.

     Did you consider adding some stream-splitting and merging pipes, 
like those in the SCC package [2] or those described in the last 
Monad.Reader issue [3]? Your arrow-like combinators seem well thought 
out, but they don't go very far.
