I assume this would require obtaining and installing a security certificate, like for secure HTTP (HTTPS) on a Web server. Does anyone know for sure if FTP/SSL requires a security certificate to be installed on the host machine, and if so whether you can install a certificate on Windows XP Pro or does it require a Server OS?

Thanks for the info. The link you provided is just for the client, it looks like there's an open-source server available too:
