I agree with the scenario. How would an (already deployed) node know which metric it is supposed to start optimizing for? I believe that intermediate nodes need to make the same optimization as the node which has the event ("intrusion") which it wishes to report. (Maybe I'm wrong, cause my the parent selection code in my implementation currently says, "return 1;") -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works IETF ROLL WG co-chair. http://datatracker.ietf.org/wg/roll/charter/
