I'm not quite sure what you mean. Right now, I am subclassing
twisted.protocols.ftp.FTP and selectively overriding methods such as
ftp_LIST, etc. Is there a better way?
And I'd be glad to help with the rewrite if I knew where to start, as
it looks like I will be doing quite a bit of work with it.

I thought it might.
To answer your further questions, I'm not that experienced with
programming the FTP or SFTP protocol (yet...) so I don't know a lot
about the differences. I want to use SFTP eventually for security
reasons but figured that FTP would be simpler to start out with. If
they're that different, perhaps I should start looking into SFTP from
