 flashproxy. This involves librarifying obfs2 in some way, and/or
 implementing flashproxy within the pyobfsproxy framework. This should be
 the easiest way of doing this ticket.

 My guess is that it's easiest to port the flashproxy code to
 pyobfsproxy/Twisted. Here is the main event loop, which could be rewritten
 with Twisted:
 https://gitweb.torproject.org/flashproxy.git/blob/23699fdfeb59473d69bea3306a150c7e743e824c
 :/flashproxy-client#l877

 The WebSocket implementation is a couple of hundred lines and can probably
 be directly copied:
 https://gitweb.torproject.org/flashproxy.git/blob/23699fdfeb59473d69bea3306a150c7e743e824c
 :/flashproxy-client#l203

 The HTTP WebSocket request handler might be a little weird, because it has
 to hijack an HTTP channel and turn it into a normal socket. But maybe
 Twisted doesn't make that hard.
 https://gitweb.torproject.org/flashproxy.git/blob/23699fdfeb59473d69bea3306a150c7e743e824c
 :/flashproxy-client#l507
