	right model, but (imho) 180 degrees out of phase.
	think IPv6 only islands w/ a thin veneer of IPv4
	(say a /28) on the outside.  the ALG's to support
	this are not well defined, with the IETF reconsidering
	work in this area.  some call this NAT-PT, my favorite
	is the CERN-IVI box... which might see the light of
	day 3q08...
