My understanding is that SSH port forwarding works only with the
control connection with the FTP protocol as it stands. Both existing
server code (wu-ftpd) and the FTP protocol are a rat's nest of
historical legacies which we would be better off not inflicting
on the next generation of software. (Speaking as a very minor
beta tester of wu-ftpd.)

If people want a text-mode file transfer, they'd be better off fitting
it into the archtecture of ssh/sftp and paying attention to i18n issues.
