Brian,
One suggestion would be to use an in-line X-10 controller on each light and use the X-10 XPT transmitter with a multi-function switch face. This is a wall mounted transmitter that sends out X-10 ON, OFF and DIM, BRIGHT commands. You can purchase several different face panels that have many switch options. This would allow you to use one switch to control many things. These are décor style switchs so you would more than likely need a different plate.
