Hi, this is to start a 2-week working group last call on the revised Algorithm Implementation Requirements document, ending March 11. The draft is at: http://tools.ietf.org/html/draft-ietf-ipsecme-esp-ah-reqts-01. We should have last called the draft a while ago, and I apologize for the delay.

Section 2.2:

It lists NULL ESP as a MUST. Wasn't this a MUST a leftover from the old
crypto export restrictions? While I think NULL ESP is a good debugging
tool, and a good replacement for AH in general, I don't think this is
really a MUST item (unless you would actually advise people to migrate
from AH to ESP NULL, in which case I'll cheer on this MUST)
I think we do want folks to migrate from AH to ESP/NULL. That's why we
made support for AH a MAY a while ago.
