Hi Jesse,

Yes, I understand that the goal is to provide an abstraction layer for
naming systems that doesn't rely on control port hacks -- and that's
great!  My primary inquiry here is about whether the DNS protocol
might be a better-suited protocol for Tor to use for talking to naming
systems, rather than a Tor-specific protocol as is proposed now.  I
don't hold a strong opinion on this; I'm mostly just curious whether
it was considered, and if so, what led to the decision not to use it.

Cheers,
