You don't need to give your dom0 external interface an address.

For example, I have:

dom0:
fxp0 (connected externally) - no IP address
wm0 (connected internally) - 192.168.1.11

domU 1:
xennet0 (bridged with wm0) - 192.168.1.12
xennet1 (bridged with fxp0) - external IP address #1

domU 2:
xennet0 (bridged with wm0) - 192.168.1.13
xennet1 (bridged with fxp0) - external IP address #2

Or have I misunderstood your requirements?
