Thanks. I wish I could say I thought of it, but I didn't. I stumbled across the idea on the net, when I was looking for something to do to remember a friend of mine who died. He would have loved the idea. I'll have a look at the automation stuff. I need to be able to read gps data, and send it back out over a TNC to a 2meter ham radio, so I can find the darn thing again. I also need to be able to record still pictures from a digital camera and record a movie from a webcam... all without resorting to xwindows if possible... as I plan to run under linux booting into console mode... with no monitor. Thanks for the kind words!

Actually, as for controlling devices... you might look into the home automation realm. There are some Linux-based solutions there, probably including security cameras and such. Hal
