A bit of clarification on why I would want such a capability (and, in 
truth, I have it today but I wanted to make it more automatic and 
available to anyone else).

Lets say that (hypothetically) we want to set up a firewall, dmz, 
whatever so that we can (hypothetically)do some attack testing against 
the systems.

To say the least (at least in the USA) this is very much frond upon on 
the real Internet.  So, set up a real heardware network ... this gets 
expensive real fast.

So, virtualization to the rescue.  Set up your network configuration on 
some very private networks (yes, they will need their own dns, dhcp, RA, 
etc., etc. services).

I can do it (and have) but I thought this might be useful to others.  
Obviously, this update should be accompanied by some documentation 
updates which explain what can be done.
