No need to install any runtime or content on the slave computer(s);  when the master computer sends a render job off to the network, it sends the selected frame of the scene, along with all OBJs and texturing JPGs.  So, the master machine's Queue supplies everything needed to the slave PC's Queue.  When the slave's FFRender64 finishes the render, it returns the result -including any separate passes needed- to the master.

P.S.     The colored lines in my diagram represent Cat6+ (aethernet) cables.
