Thanks Blue,
So, just so I fully understand. What I need is 3 IR LED's all with the widest range of possible frequencies (to avoid overlap), and then I need 2 receivers in each device to match, and pick up the frequencies from the other two?
Then the Microcontroller can check for both frequencies and if both present, light the lights?
Or will one IR receiver be able to pick up multiple frequencies, and can the controller still see both?

On a related question. How do universal remotes work? I know you program the remote with a key that then works with your TV. Could these devices use the same function?
For example, if I programmed the Microcontroller to have unique ID's...so all three devices had a unique ID, could the IR transfer that information to be picked up by the receiver microcontroller?
If this is possible, then I could just use one standard 40KHz IR LED and send the information instead of frequencies.
