So far, i'm not ready to "turning everybody loose" with it so far.
If someone made a business case for submitting jobs via ftp, i'd surely be glad to talk about it. If the need could not be met by existing standard practices, i might be swayed to using it. So far, i've not seen one (with the exception of a few cases where output was "picked up" via ftp).
