The version of unzip on my system (v. 5.41) has a `-P' option where you
can specify a password; the man page warns that using this option isn't
secure.

If the zipfile module doesn't accept passwords when opening a zipped
file, then could you use an os.exec*() call and include the password as
an argument to unzip?
