Hi, A few of the smart cookies at ERTOS/UNSW have designed a great little add-on board for the Linksys NSLU2 (also known as a Slug -- http://www.nslu2-linux.org/).
It gives you a serial port, a remote reset and allows the device to be powered over USB -- and it all fits inside the standard case! This means you can carry around a whole ARM development platform running Linux, or L4, or something you wrote yourself, all in your pocket. It is such fun I'm investigating how we can get these out to others. If you're interested, please go to http://www.netux.com.au/nslu2/ and tell me (there's also some photos). The price will be ~$20AU, but as with any electronics things vary wildly based on the quantities you buy (which is why I'm asking). We'll probably release the plans, but the genius of it is the small size of the board, which most people can't (easily) make at home.
