A way out there idea... if there is a solid target (steel, concrete) have 3 or more 
microphones, piezo's, or other vibration sensors connected to it. Monitor received 
analog signals with a fast micro, from time difference between signals triangulate 
position on the target that was struck. Probably not as easy as it sounds, but might 
be doable.
