Don't be afraid to read Twisted's source code. It can be difficult to
get into the Twisted mindset, but once there you'll find it's not all
that complex; it's just Python. It has history and idiosyncrasies,
but, contrary to protestations of its legs being missing, it is being
actively developed. From what I've read so far, Twisted also seems to
have strongly inspired asyncio, the new async library in Python 3.4,
so you're not wasting time on it. I suspect using Twisted with asyncio
is already possible, but, by the time we get to Python 3, I think
it'll be simple, so migrating will not be all-or-nothing.

Then, if you get stuck, don't know where to start, or think you're
doing it wrong, talk to me. I may not know the answer straight off,
but I'll help find it.

Gavin.
