Comment (by asn):

 Yesterday and with the help of dcf, I managed to use obfs-flash (using
 instructions from comment:17) to bootstrap a Tor client (using the
 facilitator from comment:40:ticket:9349). Some notes from my adventures:

 * txscocksx is a dependency for obfs-flash. We should mention that in a
 README or something, and add it to a setup.py maybe.
 * I was getting:
 {{{
 Traceback (most recent call last):
   File "./obfs-flash-client", line 270, in <module>
     sys.exit(main(*sys.argv[1:]))
   File "./obfs-flash-client", line 265, in main
     obfs3_flash(reactor, client, opts.obfs_out, opts.fp_remote)
   File "./obfs-flash-client", line 217, in obfs3_flash
     ["websocket"], [fp_client, '127.0.0.1:%s' % fp_local, fp_remote])
   File "./obfs-flash-client", line 189, in pt_launch_child
     StandardIO(sub_protocol, stdin=sub_proc.stdout.fileno(),
 reactor=reactor)
 TypeError: __init__() got an unexpected keyword argument 'reactor'
 }}}
 Not sure why. I just removed the `, reactor=reactor` part.

 * If the reactor was never started and then obfs-flash-client fails, you
 get errors like this:
 {{{
 Error in atexit._run_exitfuncs:

     cleanup()
   File "/usr/lib/python2.7/dist-packages/twisted/internet/base.py", line
 577, in stop
     "Can't stop reactor that isn't running.")

     "Can't stop reactor that isn't running.")
 twisted.internet.error.ReactorNotRunning: Can't stop reactor that isn't
 running.
 }}}

 Apart from that, the whole thing worked nicely!
