IESG proposed statement on the IETF mission

Scott,

How are you interpreting "has to" ?  Are you implying that IP can't run without MPLS (for example) ?

Corollary: Anything that has to run everywhere IP runs.  This pulls in
protocols which need to establish state at every IP hop, not just
waypoints (e.g. application proxies).  The one that's on my mind is
MPLS.
