"There are numerous X-10 remote control modules available for lamps and small appliances. Some are RF modules, so you don't need direct line-of-sight or a particular plug-in that sends signals over the building's wiring."
I use a X10 Powerhouse Transceiver Module Model TM751 for exactly this purpose. It has a built-in RF controlled outlet and, in addition to being independently operable from a hand-held RF linked remote control called a PalmPad Remote Control Model HR12A) the TM751 also relays anything that it receives from the remote control as an X-10 message through the home wiring. This particular device and its wireless remote control can individually control up to 16 independent X-10 modules scattered throughout the house.
Sad to say the only practical use that I've used if for so far is to turn the christmas tree lights on and off, plus control about 3 lamps in our living room! Since I also have another 10 X-10 device controllers, future uses (not yet implemented) will be to allow me from my bed or easy chair to control the porch and post light, my driveway flood lights, and perhaps an attic fan, all with a hand-held RF remote control. Why I would want or need to do any of the above, except for the christmas tree, is another question! :-)
Quite honestly, I haven't yet found a great deal of value in X-10 technology, except as still another cute toy having very little practical utility. I suspect very few people have a need to remote control anything except an inaccessable outlet for which the X-10 products that I own (and received as a gift) seem like a bit of an overkill.
