At present I do not support this proposal.

Dean,

I totally agree that we should focus on the problem statement itself in Fukuoka
since this problem statement has something new concept for Policy SIG
and Fukuoka will be first meeting.

However, I don't think this proposal needs to be withdrawn to focus on the problem statement in Fukuoka.

Certainly, in past meeting, we made it clear that we can discuss "problem statement only presentation" first,
but that is optional.

Regards,
Masato

Yeah I think this is a bit of a radical proposal to accept at present.
I'm not convinced we should be supporting CGN in this way, nor am I a
fan of seeing more and more information make it into Whois which might
not be the best place.

I would like to hear more from Hiromi-san about the problem statement
and how this might be solved, but I'm not at all sure I would support
the current proposal.

Would it be possible to withdraw the proposal and use the scheduled
time during the Policy Sig for an informational session to allow
Hiromi-san to present to the community the problem here?
