Thanks again guys.

I would like to look into the computer solution, so I'd use software to program the dim settings and all that. Then I wouldn't even need a maxi-controller.

Can anyone recommend a nice intuitive (and cheap) piece of software that does this? Are any available for a mac? Not a necessity, but I'd rather it be on my mac.

The Harmony can certainly send commands to the IR543, in fact, I have that part set up already, I just don't have any X10 stuff hooked up for it to control. ;-)
