I basically agree with EKR's review, but have a few additional comments. I
think it might be helpful to get them to try separating out the components
of HIP that EKR identified and think about other possible options to replace
them. In particular, either though experiment or careful analysis, I think
they need to explain what benefits the cryptographic identity binding has
beyond simply separating the identity and location. If they can't come up
with a very good reason for that, then generating the identifier
anynonomously or by hashing the DNS name
