Fair enough - answer below. =)

Annual renewal required of the registrant and annual
registrant-data-verification required of the registry (whois poc
verification or equivalent). Or, in the case of ULA-C, perhaps
pentennial renewal and verification would be adequate and appropriate.

...Or maybe annual for those blocks which the registry is providing
reverse DNS and pentennial for those with no service beyond basic

See my previous statements regarding the impermanence of organizations
and their networks.
