While I admire your forward thinking in not mentioning scp, I will fault you with sftp, as it requires an OS account on every supported platform. This is overkill for moving files. I have leaned both towards rfc-1867 transfers when I have a web server available, and stunnel configured to launch tar xf when I don't. I'm also about to go to production with a tftp server as a bridge to smb3. The tftp client is so elderly that it is constrained to 512-byte UDP packets - a true museum piece (running VMS).
