at $long_ago_job we'd use a pxe-netboot image; effectively DBAN
(http://www.dban.org/).   which only really works if you have another
server in the remote location to act as the pxe server.    maybe if
you were really playful (and had throw away hardware to try it on) you
could figure a way to extract the dban iso into the boot partition of
the remote machine, do a reboot and let it go?

about all I can think of.

Even the Magic 8 ball has an opinion on email clients: Outlook not so good.
