Re: eliminate AH -- unanimous



	 Before the WG eliminates the AH, we must remember that there are other
	 protocols being developed that rely on the AH option, specifically Mob
	ile
	 IP.  Mobile IP control messages (Registration Request, Reg. Reply, BIn
	d
	 Update, Agent Advertisements, etc.)  all rely on IP AH to provide
	 authentication.  If AH is dropped then Mobile IP will be forced to
	 implement its own form of AH mechanism.

Bill's suggestion is not that the functionality of AH be eliminated,
but that it be eliminated syntactically as a header distinct from ESP.
ESP with authentication and null encryption does the same thing, but
with small changes to the definition of what is protected.
