This is actually seen in quite a lot of community networks: you use "the
Internet" as a backbone to connect other sites. But you still stay
inside your ULA network for the services.

To name a few networks I am aware of that use ULA and have their own
registries:

- DN42 (https://dn42.eu/home)
- Freifunk (https://freifunk.net/)
- Anonet (http://anonet.org/)

If either of these networks would join the others, there would be ULA
collisions today.

The requirement is mainly uniqueness. Services like whois and rDNS are
very welcome from an operational point of view as well. Internet routing
is not required - for this we can use GUA.
