My observation here is that IPv6 addressing seems to be LAN-centric
rather than host-centric. That is, it's driven by the number of /64
LANs deployed rather than the number of individual computers.

Speaking off the cuff, I think I'd shape it like this:
1. Ask IANA for a /16 delegation of of the existing ULA space, e.g.
FC42::/16.Failing that, simply assert regiistration over a portion of
ULA space e.g. FD42::/16.
2. With a mostly automated web-based system, accept registration of
/48's within the space.
3. A registration account costs $10/year. No concept of organizations;
just accounts each billed seperately.
4. All /48's in the account must be contiguous to the maximum extent
possible. Each /48 registered costs an additional $1/year. In ULA
parlance, each /48 is "one Global ID."
5. Private registration available if desired at no cost. If private,
ARIN will publish a relay email address that can be used to contact
the registrant's real email address. They'll publish no other
information. After all, do we really need to know that the DOJ is
using a particular range of private IP addresses privately inside
their private system? I don't think we do.
6. RNDS delegation in the public DNS if desired. Let the registrants
decide for themselves if they want leaky name lookups to lead back
inside. Could be very helpful in a large private network where you
don't want every participant to have to plug lots of exceptions into
his DNS server.
7. Registration is non-binding. ARIN guarantees only that if both
networks participate in registration then they won't have conflicting
The $10 supports operating a heavily automated registry.
The $1 provides mild back-pressure against wasteful consumption of /48's.
The contiguity requirement mildly encourages smart aggregation practices.
