I don't have a controller, but don't the reefkeeper controllers from digital aquatics use a phone line or network cable or something to connect the head unit to the powerbars? I did a bunch of research on them awhile back and really like them. They have hub modules that allow you to split the line as well, so you could run a single line (phone or networking cable as it may be) through the wall down to the basement, and have the option of expanding to many different modules and powerbars as you need/want to.
