Hi George,

Thank you for writing this draft, this is an interesting perspective.
There is one point you do not mention: what if the IPv6 node is using
directly or indirectly IPv6 in IPv4 tunnels for its IPv6 connectivity?
For example, it may derive a 6to4 prefix from its home address
and then uses MIPv4....
There are extra complexities here that I'm not sure I fully understand.
Is it a problem space that you intend to cover?

	- Alain.
