As from the post I made in hardware, here:
https://bitcointalk.org/index.php?topic=37451.0A friend and myself are looking at creating a remote, network controlled power switch, for those of us with clusters located in other places, like all of the way downstairs. So far it looks like it connects to a computer via USB, wires to up to 14 (!) computer power switches, and supports a keep alive on the computer it is wired to via USB in case it locks up, and will reboot that one as well. Price ranges so far looking like it could be around $50 USD (Or about the same BTC) + shipping from here in Canada. Other possible options include custom cases for it, like mine will likely be in a grey skull so I can make bad jokes about "by the power of greyskull!" We are working out details and software right now, let me know if people are interested. 3D printers are awesome. Send me a PM if you have interest :p
