Uhhh, how would that work from the human side? Can you accurately put your five fingers down exactly where you want? What kind of mapping application would use five simultaneous touches? A segmented sensor (as used on the old plato terminals 8x8 resistive patches) would probably work, but what kind of resolution are you wanting?
