So I am wondering what people think. Is there a hybrid that we can use?

That is, for NERD it is all or nothing. But a typical ITR needs some  
but not all mappings.

How about this:

(1) Have an ITR, when it boots up, ask its map-resolver for all  
mappings it might have cached.
(2) It may not eliminate all Map-Requests but maybe a large number of  
them.
(3) Does require the map-resolver to be a caching system.

Comments?
