Yeah it works fine, you can't be on the net at the same time though, unless you are trying to render using a "over the net render box", use your slowest machine as the server, don't have it connected to the internet, just to your LAN, as it will just send out the packets, also on that machine have the bryce file open and in the render settings have it render to host, that way as its sending packets out to the other machines, it will render a tile while the others are busy. It works fantastic, Just gotta make a seperate TC/IP config for just network rendering is all.

Do atleast one thing a day that scares the hell outta ya!!
