So in this kind of deployment we do anyways maintain the session(or binding in terms of DHCP) database on the box. Having said that I don't think storing client information is a problem (at least in this deployment). The only extra thing which we would need to store is a 'nonce'. This is a heavy burden for the working group to take on for a small deployment. Can you go into some detail about why this is the right way to solve the problem, and what bad things would happen if you didn't have FORCERENEW? I'm sorry to be stubborn about this, but you're talking about a DHCPv4 protocol extension, and as you know from another draft that just went to the IESG, bandwidth is limited for the DHC working group—we've had presentation marathons at the last two IETFs, and I've had to chivvy presenters mercilessly just to avoid running over the generous time slots we've been given. I feel really bad about doing that, and so I'm going to push back on proposals like this if I don't have a clear sense of their broad utility. I say this sort of wearing my working group co-chair hat and sort of wearing my working group participant hat—as a participant, I don't see the broad utility in this proposal, and as a chair I see a lot of work in my future. So please, give us a clear sales pitch for why we should feel good about taking on this work.
