I've got no problems to include our work into the known mechanisms
draft. However, our draft does not explain an existing mechanism
but proposes the use of "delivery aware" DNS names for request
mapping in peering systems.

We work on this issue. Indeed, we are about to propose the exchange of
"mapping tables" (PMT) during the peering process. A tree based DNS-MS
system simplifies the peering exchange especially if footprints are
