It seems that most Perl module names try to be as straightforward as possible, giving a good hint as to what their purpose is. Maybe your module would be more aptly named Net::FileTransfer or something like that?
If you're into Lisp at all, you might be able to get some useful ideas from the Emacs TRAMP package (Transparent Remote (file) Access, Multiple Protocols, what a mouthful of a name). It works a lot like the ange-ftp Emacs package, except it can use rcp, scp, or even stuff mimencoded files through a ssh or telnet session.
Any chance that you have your code posted where others can play with it?
