I agree with Michael - IPv6 PI is not perfect but we desperately need such
policy to help in adoption of IPv6 in the US - or otherwise we will run 
out of ipv4 space before majority are ready.

If there is enough interest from research and engineering folks then
the thing to do is to form open design group and get the initial
software to test the concept and polish the design. Have that all 
available as maintained internet drafts so if/when shim6 fails an
alternative is right there to just take over and make a WG.

The activity need not be "officially IETF-sanctioned" (although that
would be nice), it just that IETF needs to be aware of it and know
that many if not majority of those involves are those also involved
with IETF.
