I read this as they simply have not filled the paperwork, because if
they did the extension would have been automatically granted; is it what
you meant?

- Short-term the only thing early adopters can do is to obtain one or
multiple /32s as discussed earlier.

- For medium to large setups, MHAP is entering commercial development; I
cloaked the technicalities for a few months to give a competitive
tactical edge to the company that develops. No intent to create a
proprietary protocol though; when the code is ready to ship I will
publish the latest draft.

- For smaller setups Microsoft is working a multi-address solution along
the lines of what Christian Huitema proposed in Atlanta:
http://arneill-py.sacramento.ca.us/ipv6mh/Dual%20Homing%20Experiment.ppt
http://arneill-py.sacramento.ca.us/ipv6mh/HostCentricMulti6.ppt
I do not know what the current state of development is though.

I have made that very point myself many times. For that reason and for
the sake of launching IPv6 I am willing to look the other way if we
assign /32s to end-sites (which is a blatant violation of today's
policies, but there is no other solution) as long as we keep the policy
tight and can enforce it later.

It is clear to me from recent meetings and presentations that the issues
that Craig was raising here recently are not only Cisco's problem and
that there needs to be a PI-like solution as well.

Michel.
