I thought that cups had some 'as root' hack, where a 128 bit secret was
passed across, to prove that we are the root on the same host?
What we really want however is to ensure we act as the user, not as the
system, but without their password, and preferably also on remote hosts.
We don't get this stuff right at the moment (I'll file another bug) but
a cups user/cups password would make it worse, I think.
I think what we need is a brainstorm with the CUPS folks, who are known
to hang out in these parts :-)
