That is not a type of multihoming M6 should address. Instead,
it is purely a mobility issue and is useful for smooth handover.

With mobility, M6 should address multihomed base stations,
multihomed home agents, and multiple home agents at different
subnets (MIPv6 does allow for multiple home agents but only
in a subnet, which is mostly useless), all of which was, in
my experience, handled automatically.
