Hi Dave,

I don't know if you've gotten far enough to discuss code layout/design,
but it would be really cool if you follow the "sans-IO" approach for the
design of the actual "OR protocol" part of the project.

A great example of this is the Hyper/H2 libraries by Cory Benfield for
the HTTP2 protocol -- this what drives Twisted HTTP2 support as well as
threaded (blocking I/O) servers.

   https://github.com/python-hyper/hyper-h2

There are several advantages to this approach:

 - makes for a nice and clean separation between core "protocol stuff"
   and the I/O.
 - the above makes testing easier and cleaner (e.g. end-to-end tests
   that don't use any "real networking", all in-memory)
 - allows use in blocking / threaded implementations but also async
   (event-based) implementations (for example, someone could then
   leverage the bulk of your work to make an asyncio binding without
   having to re-write all the parsing and state-machine code)
 - it's the new hotness

I'm usually idling in #tor-dev as meejah, ping me any time

Good luck with your project, sounds interesting!
