Link requested subdomains to the relay's fingerprint, and require all change/update requests to be signed by the node's keys, and have some validation that the node can be found on the network (and is an exit node). This will ensure only Tor exit nodes can apply, and that nodes can only change their own subdomain, and even makes it reletively scriptable, if desired.

If so, I'll write a small something that will allow adding new subdomains to it. So that you can always add and update subdomains on it.
As long as you don't let other people do that themselves. That would be open to abuse. GD
