I'm working on it! At least, I am looking at microcontrollers that have ethernet built in, and some amount of I/O pins. I've got one picked out, but it has availability problems, so I am waiting just a little to see if that gets resolved. I still need to get the development software for it, and work out how to use the Linux real-time ethernet driver. I am hoping to do this this fall, and have an add-on board that will be quite cheap. It needs one of these all-in-one microcontrollers, an ethernet jack, a quartz crystal, some voltage regulators, and not a whole lot else. I also need some method to set the IP address, either USB or serial port, I guess.
