Infra Red communications -- I don't know if this is what your looking for, but I recently bought a wireless microphone from Radio Shack that broadcasts on an unused FM radio station. It is small (about 1 inch x 0.5 inch x 0.5 inch), and it has a clip on the back as well. You tune it to the frequency you desire, and it costs $20. If you haven't already, maybe you should consider it. Allan R Baker arb2@uafhcx.uark.edu
