Hasta La Motion!

Hi guy i one question when it comes to satellite rendering, what would one need to connect all the comps together how is that done? what hardware is needed for simple render farm at home. Sp basically when one sets up a render farm with lets say 3 comps then those 3 comp will be used by xis to render each frame making the process faster then with one? If i decide to purchase Xsi advance how hard is to sed up simple render farm with 3 pc. Does cinema 4d after effects support satellite rendering?

Thanks
