As far as directionality goes, I had thought of using an IR laser as the sending part, and IR detector(s) as the receiver. Perhaps a LED in a tube would do as well, and would certainly be cheaper.
I spoke of modulation in my original post because I am looking for a way to make each detector unique, in that it cannot be triggered by stray signals from other detectors, or ambient IR.
