None of this should be a problem, if you configure correctly as others have indicated... But a couple tips...

In Windows2000 Server's DHCP, you can assign each receiver's ip by it's MAC. Then, in you DNS, you can create a friendly name for each, so if you install DisplayServer on each, you can access each one easily...

http://receiver1
http://receiver2
etc.

I am doing this, and it works really good. I just wish there was a version of DisplayServer out there without that volume hack!
