The way all this would work, the virtual net would look just like an ethernet
to both the host system (as network interface tap0) and to the virtual systems
(as network interface eth0) ... these can be treated as any other ethernet
and if the host machine has an uplink connection, it can route between them.

If the host has an ethernet connection, the host can either route between the
two, or it can setup bridging between the two networks so they seem to be one
larger ethernet.  This allows arbitrary firewalling to be potentially setup
between the real network and the virtual network, or it allows for the virtual
network to act as if it were directly part of the real network.
