This is an interesting thought.  The IPSEC framework is also potentially of
great interest for dial-up access at relatively low speeds.  In this case,
compression contributes strongly to delay, and thus to performance as
perceived by the user.  It would be very unfortunate if IPSEC were to
preclude effective compression.

This argues, I think, for incorporating optional compression into the
framework itself, as Bob suggests.
