Another option that we use is to have an XML-RPC server running
as root on localhost, accessible from the web server. This
server is written using the standard python SimpleXMLRPCServer,
and handles a limited number of procedures. Some of these
procedures, such as running ``make'' in the etc/postfix directory,
do not have serious authentication. Others have stronger methods
of authentication and restrictions.

It would be a great improvement if the government respected individuals
rights as much as they respect the rights of the caribous.
