Yes and I think we've distilled "locator/identifier separation" down to: To the extent possible, identification functions should stop depending on location-dependent inputs. However, (1) we are still unresolved about what network-layer support is needed for identification -- for example even if we need whole node identifiers, stack names, etc. -- and (2) we don't have specifics about what to do about "legacy" identification. > Also, can we say anything about CEE/CES?

I don't think it's a good idea to declare either approach the long term winner, since we can't know what the future holds and even if one wins there will be new approaches by then. A CES approach may be able to migrate to CEE in the long term, but also vice versa. Ideally we should document how they interwork and make deployment of both easy -- whether both get deployed or not, that's architecturally a good idea. Joel M.

My point is that we do not have a good description of why.) I am glad to _help_ but I hesitate to commit to writing it up all by myself by the deadline (no time!). If you, for example, want to take responsibility for the text, we can have some good phone calls.
