OK, I see now. When Tim first contacted me he came across with a certain sense of naivety that doesn't seem to be supported by his interactions here, and he led me to believe that he was talking about new ICMP messages for prefix delegation. Then later, when I suggested to Tim that RS/RA could be used for the PD, he told me that yes in fact that was what he would be proposing and he ended the discussion with what I could only describe as a certain sense of self-righteousness. Now we come to find out that its *both* RS/RA *and* two new ICMP messages. That's a lot of messages, and it might lead one to ask that if there needs to be two new ICMP messages why not use them for the prefix delegation too and avoid overloading RS/RA and tweaking specs? (But then I guess the proposal wouldn't be any much different than those that were offered several years ago?)
