  but you can configure vsftpd to have secure connection:

http://wiki.vpslink.com/Configuring_vsftpd_for_secure_connections_(TLS/SSL/SFTP)

would that not address that issue?  i'm not arguing against secure
communications, only that that manual page so cavalierly dismisses
vsftpd when it seems clear that you *can* configure vsftpd to be
secure.
