I think it does fix the problem or at least helps the problem Terry. The real question, as you state, is the Internet ready to use this solution.

And netflow caches smaller and EIDs in the underlay possibly private and more secure. All good things for USERS.

Agree 100%, but Prague will be used to brainstorm. Once we do that, we need to DECIDE on those priority items. Hope you will be there to contribute. You have a lot of experience with LISP deployemnt and can bring a lot of value to the discussion.
