For many functions such as doing djbdns zone transfers where one
wants to restrict the copies by IP address, but doesn't need to worry
about intermediates seeing the data, or dealing with setting up ssh key
security, using rsync modules provides adequate security without the hassle.
One can easily specify the directory a remote host can access, and allow
only that IP access to the directory.

When only cops have guns, it's called a ``police state''.
