[Laser] 5mw laser transceiver kit

  Pondering, I wonder if half-duplex - despite the simplicity - is a 
good idea.  Due to the narrow beamwidth, alignment is critical so 
instant pointing feedback would be very handy. In half-duplex, I can 
envision Johnny and Billy saying "Can you hear me now?" until they give 
up and head for the Wii, but hearing the hiss of the other end in 
full-duplex might help avoid that frustration.
