2) I have looked and looked and can find zero/zip real world examples for network routing (as opposed to the bridge style). I'm presuming that this is what I must have since all machines need public/routable addresses.

Use the bridging (not the nat).  The machines will have public/routable.
We are doing this now.

OK. What I had read previously had point me in the routed direction, so I had not tried the bridging as much.

4) Another key point is that, for domUc, there are several IPs listed.
The reason that is there is for our web server which has numerous IP
addresses bound to it. HTTPS likes having its own IP addresses, and we
need to be able to bind multiple IPs to that guest. Is THIS possible,
or are we prevented somehow from binding multiple IPs to a server?

This is possible but you only list one IP in the xen config itself
and then start up the others once the machine starts up.
We have one xen instance that has four IP's right now and it is
working fine.

I'm guessing I'll need to turn on proxy arp on dom0 for this to work, right?

BTW, do you mind attaching or e-mailing me directly a copy of your domU config so I can check it versus what I have? I have tried so many different things, I'd like to see a good, clean example that is known to be working. Feel free to mask/change anything you need to for privacy.

Thanks.
