We've discussed stackable GSS-API mechanisms to provide such features as
compression in the KITTEN WG.  It's certainly doable.  But as Dave
points out, the real trick is in re-using whatever compression is done
on-disk to reduce the CPU load ont he server.

(The same does not apply to encryption, for a variety of reasons.)
