This is really cool
but some of the stuff I'd like to do with it would require me to get my X-10 stuff working with OS X which might take some doing. (My current X-10 controller is serial only so I'd need to setup a serial/usb adapter to make it work and find OS X software to talk to the X-10 controller.) I found a usb controller
but I haven't found any Mac OS X software for it yet.
