I think you mean vsftpd? Problem with FTPS is that it *can* be
problematic with firewalls (not necessarily your own which you can set
up correctly, but on the client side).
ProFTPD may be a good option as well. It should have a mod_sftp module
which theoretically could be used in tandem with ProFTPD's native
chroot'ing stuff. Never tried it though.
