Re: Discusses on GIST (draft-ietf-nsis-ntlp) regarding query messageinterception

Can I echo that.

I have also cleared regardless of the RAO decision.

My personal opinion is that RAO is the less good option, and (if it was up 
to me) I would suggest retaining the current mechanism.

Thanks,
Adrian

Just to be clear, I am *not* asking you to change the document back to
RAO. I have cleared my discuss regardless of it stays with the current
intercept scheme or moves back to RAO. I actually missed the part
where the IESG came to the conclusion that is needed to be changed
back to RAO but if that's what the AD wants, I'm ok with that..
