I like this proposal A LOT 1) its simple 2) its tractable. 3) its informative both of the end system and intermediate system capabilities
but also because 4) it will provide us with immediately useful information to inform current activities like the KSK roll, if only about the rate of system adoption of current code, into the field. I think its worth going with. If this was done soon, we'd be able to use it soon. We'd learn things like the average length of DNS resolver/forwarder chains in systems which consistently deployed it. We might even learn which intermediate players are 'blockers' of upgrades from the kind of heuristics we do a lot of in reviews of routing, via tracceroute/ping differential analysis. I really like this proposal. -George
