I think that we are working on MOPex because we are concerned about running out, and we want to establish the rules for extending things early on. But, I don't think that we need to rush to defining "RPLv2": which I think would imply that CAP would provide the useful info. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | network architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [
