On re-reading this, I realized you're probably actually asking something on
the order of 'can nodes interact with the Mapping System with ordinary IP
packets, or can they only send LISP-encapsulated packets to it'.

I honestly don't know the answer to that; I _think_ the spec calls for
packets to the mapping system to be encapsulated (for historical kludgy
reasons that I never liked, so I try not to think about this corner of the
design), but whether a Map-Resolver would barf if it received an
un-encapsulated Map-Request is probably an implementation-specific question.
