It could simply respond to any ipv6 reverse lookup with a calculated
reply.  Might be a good proof of concept for a software-on-the-fly DS.

IPv6 PTR plans were discusted from time to time at the IETF (both
in meetings and in lists). The wildcard solution is not a good one
(it has too many unlimited side effects).
IMHO the best is to not provide a PTR space and to delegate it only
on explicit offline requests (for the prefix or a few individual
addresses). The reason is in general the IPv6 PTR space is not supposed
to be reliable so one should put something in it only for exceptions
(MTAs for instance: some anti-spams require a PTR to accept mails,
the IETF mailing list one is (was?) known to spuriously check this).
