just touching upon io333's comment...
Definitely check out netremote.org. That site has a ridiculous amount of information. You want to control x10 stuff throughout the house - no problem.
The way I understand it, is you can have netremote control just about anything that a computer can with their FREE software and a wifi card.
I don't have a wireless network in my apartment (yet), so I haven't been able to play around with it much yet. There are a TON of possibilities with this software.
Using this software will probably have a relatively steep learning curve for some. One would have to be comfortable reading through documentation. Probably not too much of an issue for most readers here
