Bill,
	While the DS-LIte mechanism does involve moving the NAT
towards the Core instead of leaving it at the edge, the advantage
is that you can route around it very easily as an end-user.  Every
thing the end user sends to an IPv6 destination bypasses the NAT
box completely and only IPv4 is afflicted.

	I think that will be fairly easy to deprecate over time vs. many
many edge-NATs and layers of NATs near the edge.
