If you wanted to add you're HP 3.0 Ghz to you're renderfarm, the default method would require that Bryce is installed on another machine.

Bryce will Not Render and Deligate Bryce Lightning Client Machines at the same time.  This was a previously available feature that has been removed since.

Bryce version 5.5 and later will only Deligate work to Bryce Lightning Clients when using the Network Render option, so which is the reason I recommend you run Bryce on you're slowest system when doing a network render.

I'm using a 100 Mbit switch myself, but I havent done any traffic or packet analysis to see how much activity is being utilized from each system.  Something that is on my to do list.

I wish money was not an issue, otherwise I would have a Bryce Renderfarm up and running.  But I cant touch the money I have saved up since work is speradic right now but once I get stabalized again, I can think about the investement.

Another thing that I forgot to mention in my previous posts is, from what I've heard Bryce Lightning does not support Dual Core Processor's, but I cant confirm this since I dont have any dual core systems.

I've heard about People running two instances of Bryce Lightning with Two IP Addresses etc... but I havent seen any concrete proof just speculative info.
