That is a very persuasive argument in favour of using 
mDNS for ULA reverse DNS mappings inside an administrative

Indeed.  Several folks think that mDNS is a very promising
potential direction for local DNS support.  After all, there
is a very widely deployed existence proof that it can work,
and it is apparently going to be standardised by the IETF.
