Yeah, DHCP with zones works, as well as exclusive networking
with routers and firewalls in zones.

The challenge in this setup would be to bring the routing to
life. There are setups where the GZ has no public IP address
and a local zone has a dedicated public interface and works
as a router/firewall/NAT for the whole system (GZ and other
LZs) kind of like what you outlined. I wonder if that can
work with the multiple interfaces, one of which is present
at a time ("raw", ipmp or aggr to start with). If my other
options don't pan out, I research this more - thanks for
the idea ;)

I did however want to bind at least my bridged VMs to VNICs
on the physical public interface, so they can be addressed
from the external net with that net's addresses. I am not
sure this would work well over NAT (i.e. serving CIFS from
several VMs on one public IP address is tricky), and I did
start my questions (unanswered) discussing the possibility
of just attaching an etherstub to external net like a switch,
bridging over the available one of the physical interfaces.
