ftplib pre-dates the standard logging system by a bit.

I think ftplib only prints stuff if you set its (the FTP class
instances') debug level to greater than 0.

If you really want to replace sys.stdout with something that passes the
data to a logger, then something like the following (untested) class
should do it:

class FileLog:
    def __init__(self, log):
        self.log = log
    def write(self, data):
        self.log.debug(data)

The best solution might be to subclass or rewrite FTP to really do what
you want.  I believe one of the goals of Python-3000 is better
integration of the standard library with the new-ish standard logging
system, so if you do a good job send it in.  ;-)
