They really are full fledged computers, with big possibilities. I have spent the last couple of days in the planning stage of a home automation / personal assistant project, and plan to use several guruplug computers to pull it off. Connect a mic and webcam to it, and I should be able to pull off voice and facial recognition in a system that can always be on. I'm glad the guruplug was eventually mentioned, it is the same price as the sheevaplug, but has 2 USB ports instead of 1, an eSATA port, and wifi builtin. The SheevaPlug is grossly underpowered in comparison, but it was the first.
