 stuff.

 Making it an obfsproxy module seems to be raising some design questions
 with awkward answers. An ezpt.spec file, for example, is quite different
 from the design in the ticket description (as I envisioned it, anyway),
 and so far the patch has a surprising lot of changes to obfsproxy itself.
 As it is, it's more "here's an easy way to create an obfsproxy module"
 than "here's an easy way to create a new pluggable transport." I'm not
 saying that's a bad thing, and it may actually be more useful in the long
 run.

 The need for SOCKS and ExtORPort support is a pretty important
 consideration. We should try to make those things part of pyptlib. I
 remember George and I talked about it--it wasn't so easy to do because you
 can't assume that programs will be using Twisted.

 Or maybe we should just recommend building on obfsproxy in general for
 Python pluggable transports? Use obfsproxy as the basic library, rather
 than pyptlib? It's what everyone will do anyway, because it's the easiest.
 It worked for ScrambleSuit; maybe it's a good idea in general?
