The problem is that there is no clear "best" way to do multihoming in
IPv6. So router people want the hosts to solve it, layer 4 people want
layer 3 to solve it, and so on. Who will be the tiebreaker? Someone people
are bound to be unhappy, whatever we end up implementing.

For multi-address multihoming to work, we need to know more than one
address the time of session establishment. Preferably before setting up a
session, but certainly well before the setup times out. However,
traditional multiple A/AAAA records should suffice for this purpose.
