latency? seriously... you are on a local network with ping times under 1 ms... no one, anywhere, will feel the latency effects between 2 clones communicating across a local network to synchronize their actions. anyone that says they do, well.. they are expecting a bit much.

now... running 1 per machine is much nicer to the cpu then 3 on the same cpu. but that's not latency, that's load.

and high load can, depending on the situation/drivers, starve out communications and potentially disconnect a clone. i have yet to see that happen even on my crappy little laptop, unless my network was choppy.

therefore... until money rains from heaven... multi-boxing with 2+ clones per machine it will be for me
