i guess that also in this point, we should follow the general criteria
of not making things worse than currently are.
SO the level of privacy provided in current single homed IPv6 should
be
provided in multihoming, i guess.
(a possibility could be to include the current level of privacy
support
in IPv6, just as the other current state of the art are presented.)
Good point.
I guess we can start with IPv4 where in some cases (dialup being the
prime example) the IPv4 addresses change over time.
In IPv6 the temporary addresses RFC provide a way to make it
harder to correlate packets from the same machine over time.
So I think the "do no harm" criteria means that the introduction
of multihoming support should still provide the same ability as we
have in IPv6 with temporary addresses.
