It would certainly be convenient to allow FAH to be run cluster-style at home, rather than having to administer each computer seperately. I know that clustering can be done on Linux machines, and I would expect that there is a way with Windows as well, if you set the permissions properly.
What would be interesting is to see a highly-threaded FAH client that works over a cluster of computers with differing computing abilities. It would be really cool if I could use the desktop as a centre of FAH computing running an SMP client, and when the laptops are detected on the network, the desktop would assign each threads from the client that's already running. The computing power of all systems on your network could be used in a modular plug-and-play fasion. This would require FAH clients that spawn much more than four threads, and it would require some system to coordinate computation on vastly different computers, with some slower than others, but I can really see this being beneficial in terms of Stanford being able to assign even bigger WUs and having them completed in less time.
