Review the MPR draft at:
http://www.ietf.org/internet-drafts/draft-otis-marid-mpr-00.txt

This was not referring to a reverse DNS lookup.  This record type is
being used in much the same manner as with the DNA draft but using the
_mp._smtp.xxxx.xxx sub-domain.  This would be a forward lookup and
something easily within the control of the domain owner.
