I would love to join the technical discussion but can't seem to find how to join.
Any way, I recommend the following:
1. All new NAANs will register a TXT record on their domain root with the subdomain for accessing the ARK resource, e.g.:

NAAN 99999 BY [ISSUER DOMAIN] IN a.b.c.example.com this stored as
2. Any NAAN may self add a shoulder by creating a TXT record, as follows:
which may be utilized on a different domain, e.g.:
This becoming the issuing authority for 99999/a3 (can provide it signatures, and so forth)
3. Any top level issuer must maintain a synchronized list of all other top level issuers.
4. A policy file may be stored, under the TXT record:
