> Dino,

> thank you for this and your other answers!

Anytime.

> I can see that it's possible to treat EIDs as sufficiently static to treat them as (stand-ins for) unique identifiers.

Yes, that is correct.

> I can still (quite easily) construct scenarios with drones where the EID-to-RLOC mapping on a LISP map server is not going to suffice for AAA. I'd gladly discuss this further, but it is increasingly out of scope of the current topic on the distinction between identifiers and locators.

If you want to go private, I can discuss with you. 

But note that registration to the mapping system can be signed and verified with PKI so when a requesting EID is authenticated (and authorized) to lookup a destination EID, the map-server can decide if a reply should be returned (map-servers can proxy-reply for Map-Requests).

> I'm conducting some ongoing research on this more general AAA topic, however. I can see that there is space for a LISP extension at some point to cover such scenarios. That is a highly interesting conclusion in its own right. If you 

It is my belief that you don't need other AAA solutions if your mapping system supports access-control and identity verification.

> don't mind, I shall reach out to you regarding this in some time, because you appear to be the right person for this!

Sure, anytime. Thanks.
