For PPP? Write a new RFC suggesting it and explaining how to deal
with the "chunkiness" and additional memory overhead. For JFFS2?
Bzlib compresses worse than zlib when dealing with small blocks.

There may be a couple of uses where zlib could be replaced by
something else. But even ignoring the compatibility issue it isn't
always that simple.


With a PC, I always felt limited by the software available. On Unix,
I am limited only by my knowledge.
