I'm a bit fuzzy on what exactly you'll be using the FTP for.  What
portion of the upgrade process are you proposing be accomplished via
FTP?  Downloading the .zip/tar.gz of WordPress from wp.org?

What advantages do you percieve in this method over your current
methodology (one which received a bit of a knock in the WP Podcast
#21, btw. http://tinyurl.com/3cgvd9   *grin*)
