I'd like to hear from Jeff Schiller and the WG chairs re this still open
issue.  My recollection is that there was supposed to be a small meetng to
reolve this after the last IPSEC WG meeting in San Jose.  I observed that
we had two variables affecting aligmment: sequence number size and HMAC
size.  Hugo made a suggestion to truncate the SHA-1 value to 128 bits, to
reduce the number of variables affecting alignment, but I don't recall a
decision on this, nor on the 32 vs. 64 bit sequence number.  We do eed to
nail this down so that the grand unified AH and ESP specs can proceed.
