I've had up to 4 machines running using bryce lightning without a hitch. You need to make sure you have the latest update for for bryce 5 and the latest Lightning. Load Bryce and the br file on 1 machine then load and run Lightning on the others. I use a fast ethernet switch as a hub. Another thing to look for I believe depending on the network render settings and the type of render (animation or single frame) it handles the parsing of the frames and or tiles to one machine or more depending on these settings. In other words if you are doing a single frame render and you select (each machine should process a frame) Only 1 machine will process the render. Then theres tile Optimization so if you have a single frame rendor Bryce will send small tiles of the frame to be rendered to all the machines on the network. Hope this helps I guess I could to a tutorial hmmmm...
