If you want to do this really "on the cheap" you can adapt 
cheaplightswitch on linux (maybe other OSs) to control up to eight 
devices through a parallel port on a linux box. I have built a 
two-channel version that controls two devices. Telnet into the box and 
issue the right command to turn anything on or off (with some limitations).

Glad to share experience and schematics if that's helpful.
