Perhaps this is an easy way to build a multinode grid computer. If you do not have enough plug points you can get those monstrous power extenders and plug in 10 or 20 of Sheevaplugs.
Marvell®’s SheevaPlug™ is a plug computer — an embedded computer that plugs into the wall socket and can run networkbased services that normally require a dedicated personal computer. Featuring a 1.2GHz Marvell Sheeva™ CPU with 512MB of flash memory and 512MB of DDR2 memory, the SheevaPlug provides ample processing power and resources to run any embedded computing application. Network connectivity is via Gigabit Ethernet; peripheral devices can be connected using USB2.0. Software for the SheevaPlug includes multiple Linux distributions and follows the open-source model, making the SheevaPlug an ideal platform on which to develop or port any application. The SheevaPlug development kit contains the SheevaPlug as well as all of the software tools needed to develop applications for the platform.
