So true. Just pray you never have to deal with FTPS, which, despite sharing a similar acronym to SFTP is competely different and is a total car crash. It's basically FTP over SSL, which is FTP, with all its warts, plus SSL grafted on. It comes in implicit and explicit varieties that change the way the ports are allocated (ala passive and active FTP) and it is a bitch to configure a firewall to allow is as well as regular FTP.
