  | Realistically, the ICMP based DNS stuff has certain logistical issues
  | when the number of nodes and/or the diameter of the topology gets "large".

Provided that the actual lookups are done by something that caches the
answers (positive and negative) and returns future answers from the cache,
there really shouldn't be much difference between ICMP address->name
translation and DNS name->address translation.   As it is most in-addr.arpa
(or ip6.int or ip6.arpa) servers live right near the net that is being
translated - the net traffic to get an answer isn't going to be appreciably
different either way.
