Hello bancfc,

AFAIK, the OnioNS project was never actually finished nor deployed.

It also has various engineering/deployment issues that have not been addressed
and it requires a whole infrastructure/community to work.

In general, I'm open to DNS-like approaches for hidden services, but if we can
also improve the UX situation on the protocol layer, that seems like a win to me :)
