there is no need to 'define' this approach, it has already been
implemented with success -- VanDyke's SecureFX shows this.

however, i think that a SFTP subsystem is still useful since it
implements a much simpler protocol than FTP.  if you want to reuse
existing FTP clients, than you can implement a ftp-sftp bridge like the
one from mindbright.se.
