I also would strongly prefer a solution that makes
multi-homing a native/first-class property of IPv6.

Does anyone else have any other architectural approaches
(besides the two mentioned so far) that the WG should
consider ??

Existing architectural approaches seem to be:
	1: identity/location separation; with the locator
		following the actual network topology & the
		identifier being quite independent of topology.
	2: tunneling to create a virtual topology
		that matches the addressing
