<quote> 4. Conclusions or Questions The NSRG was not able to come to unanimity as to whether an architectural change is needed. </quote> There has been a lot of discussion about the separation of identifiers and locators (in various forms) on the multi6, ipv6 and ietf lists. A lot of people seem to think this is in some form needed. I would like to know the arguments against such a change. I don't think the document has much text about this. It lists a lot of questions. But most are more "how" than "why" questions. Are there many people fundamentally against a change and if so, why? rvdp
