I would admin such a machine precisely by using a ten foot pole - That
ten foot pole can be materialized into a firewall-able machine sitting
between it and the network.

I agree that any Debian architecture needs to provide basic networking
facilities, but I don't think firewalling is a real requirement. Yes,
of course, we expect users to actually _run_ this architecture, and
they will probably be connected to the network, and thus they can be
at risk - But right now Debian installs are done with no firewalling
rules on anyway.
