Ummm, yeah, it is called stacked disciplines in sfio, stream pipes in
Onions (my Ada95 library that nobody uses), buffer slices in IO-Lite,
streams in W3C-libwww, or layered I/O in the 2.0 wish list.

I'm all for it, though I'd use my bucket brigade from Onions and the
IO-Lite memory stuff (assuming sfio wasn't good enough).
