Hi! I guess we could keep an eye on the process, though I don't know that I'd have much to contribute myself: I'm more of a crypto consumer than a crypto generator.  Maybe one of the developers who knows crypto better can join in here?

As for adoption: we're on track to deploy next generation hidden services some time this year, ideally in the next 4 or 5 months, so the window to converge on a common system is small by standards-body standards.
