Ok. Maybe I'm missing something... but when I start this way I am
currently under the impression that I have no way to obtain an
automatic IP address. DHCP away from the host machine certainly does
not work.

Am I wrong? Can I obtain an automatic IP via DHCP or some other means?

By "loaded" I meant "initialized" and not "heavily resourced". Poor
choice of words sorry.

Bridges make defining hotplug etc harder than just defining them for
stand alone interfaces.
