    I would investigate vision systems. I may not understand your exact 
    application, but perhaps you could do some rudimentary person/position 
    'recognition' with a camera in each room (Identify people by shirt 
    colour, or height, etc). If the software tracks continuously, it should 
    be able to keep who's who straight.
