RFC 2003 is a different standard with different priorities.  Note that
RFC 2401 is quite careful to say that IPsec tunneling is "modeled after"
2003 tunneling, not that it *is* 2003 tunneling.

We already have a new spec.  IPsec tunneling is specified (albeit not as
clearly as it should be) in RFC 2401.

Why is an update to 2003 required?  2003 remains perfectly satisfactory
for the purposes it was intended for, security not being one of them.
