        Wouldn't it be easier to have the Hurd running closest to the
hardware, the one on boot, have full control of the network?  Any
sub-Hurds could be running on a private internal network, and the
primary Hurd could do NAT.

        Of course, this would require something like Netfilter to be
ported.  *sigh*
