I think we’re in agreement. If the DHT is setup in such a way that to write to it you need to use your nsec to sign the 10002 post which lists your relays with the lookup based on the npub. DHT’s are particularly censorship resistant, there are lots of kinds of DHT’s and ways to use them. We’d want to have somebody double check and help with its design.

There might even be a good way to take 10002 messages from a relay and push it to the DHT. It has to be signed, so even if the original person who created it doesn’t post it to the DHT with their app, others or relays could. The other half is to then provide a web UI for looking up npubs from the DHT. That way it would work without a chicken and egg problem.
