So instead of allocating 10.0/16 addresses to your domUs, you just allocate
public IPs to your domUs.

It might help to think of the bridge as a regular Ethernet switch, and each
of the machines (dom0 and domU) as a separate physical machine.  Then you
just configure each machine as you would normally, and leave the bridge to
play Ethernet games in the middle.  Using that mental model has never
steered me wrong yet.
