X10 communicates over the electrical wires. So if you have 220V to the normal 110V USA house, it may only communicate over half the outlets (one side of the 220V). You can get over that if you install a 'bridge', but that is something else to put in.
As designed X10 is one way communication. It also is inherently un-reliable and the ones I have used 'fail on' after a power outage. Some X10 controllers re-publish the settings on occasion (once a minute more or less) but not all. So if you have a power failure, you may come back to find all the X10's on. Because of the un-reliable power where I live (sticks of TN) they are not a good choice. There is a device that allows Linux or Windows to talk X10, but I don't think it will receive. X10 was initially designed to be one way communication, so it doesn't do 2 way well. Basically to do lights on/off/dim kinds of things. Appliance modules were on/off, dimmers were for incandescent lights mainly (not fluorescent) and the dimmers often provided a chopped wave so it was electrically noisy. X10.com will sell you just about anything X10 (and more). Most of the stuff works as described, but don't over-read what you would like it to do... it probably won't. If you search hard, I think there is a fair explanation of X10 (at least there was a few years ago, if I remember right). The x10grench... Jack (There are some 10mbit ethernet over power devices and nic's out there. They may still need a bridge to another phase of power, but they tend to work fairly well. They might be worth investigating depending on what you want to do.)
