I'm sorry, but I don't have the chance of looking it further right
now, but I took a look at your code, and I say that instead of making
FTPServerFactory inherit from FtpFactory, you opted to instantiate it
inside a object inherited class. I never tried this approach, and that
may be the root of your problem. I'm redirecting you e-mail to twisted
mailing list, so people there can help you better. I advice you to
subscribe to that mailing list to get help (if you aren't subscribed
yet). You may also try the IRC channel for some help. Twisted folks
are very responsive and willing to help.
