I've been advised off list to be more specific in my requirements, which
I guess is a fair request, the only problem being a lack of knowledge on
my part to elaborate further.

Up 'til now, I've been happily using the vif-bridge script for all my
domUs, giving them unallocated ips within 10.0.0.0/16 range. I now need
to set up a xen host in a datacentre with each domU having a routable
public ip address.  The person in the datacentre wants to know how many
public ip addresses I require, and I need to make sure I have this box
setup correctly before I ship it halfway across the country. 
I know for sure that I want to end up with the two domUs having their 
own routable public ip addresses, and I assume the dom0 would need its 
own ip as well, but over and above that, I'm floundering.

At this point I probably dont need to point out that I'd like to keep
this setup as simple as possible, I'm cock-eyed from reading the many
xen networking guides google finds, and I'm begining to suspect that
even what I had assumed would be a fairly trivial setup may be somewhat
beyond my complexity horizon.

Thanks, again, in advance.
