Ignoring the "chair" scenario:

1: How far apart would the beams need to be?
2: How best to interface them to HV?

Remember reading way back at the start about this guy that had two IR
beams in his door frame.  Order they were broken in gave direction of
travel and central controller kept a count of people as they went in and
out so it didn't turn lights out until it knew there was no one left in
the room.

He couldn't figure out why lights were still on one time and no one was
in the room.  Then he remembered he'd carried a chair into the room
which was slightly in front of him and seen as another person :-)

Nothing's perfect in this game.
