I have Bryce itself running on the faster computer and have only done it that way. Maybe it does matter which computer is the host. I don't have Bryce installed on the second computer, just Lighting, so I can't check it out at this time. I've also used a third computer in the network (1.4 Ghz laptop) and it works just the same.

The faster one is running XP and the older computer is running 2000. Just using standard network cables.
