@Sir_Boops That's GREAT! I've been talking about how I think we should do AP over tor .onion addresses and I was planning on doing it myself. I am *thrilled* someone else beat me to it.
IMO we're going to need to start incorporating petnames systems into these systems in order to make the gobbletygook'ness of those identifiers still be useful for people: https://github.com/cwebber/rebooting-the-web-of-trust-spring2018/blob/petnames/draft-documents/making-dids-invisible-with-petnames.md
(Also augh I need to finish that paper)
