Right, but do we need a pointer-based scomp at all? IPComp would
certainly be better off with an SG-based interface. Any other
users of compression are presumably dealing with large amounts
of data where an SG interface would make more sense.
A pointer interface makes sense for shash because you may be hashing
16 bytes at a time. Nobody sane is going to be compressing 16 bytes,
or are they?
Cheers,
