Minor technical detail. Obviously this is not needed for ULA-C
since the ULA-C registrant has a relationship with the RIR, and
one can assume that when they received their ULA-C address block,
they also received a code that could be used to enable reverse
DNS at http://ula.nro.net. And if their code had expired, the
NRO web page would kindly explain how to go back to the assigning
RIR and get a fresh code.

I am assuming that we would only assign ULA-C to organizations
which sign some form of RSA and which maintain an ongoing ARIN
relationship which probably includes a fee covering whatever 
services are required.

Agreed. But if we can get the five RIRs to jointly agree on
policy and process then I think that we can get the IETF to
agree on architecture.
