just a minor idea but how about making it so that if you launch a micro at some one with a pneumatic cannon (think that is what they are called) they will knock the item out of the slot they are aimed at and take that slot cloths wise.
might be a bad idea, but would make a funny hey lets try this thing actually useful for something other then throwing a micro across a room. (should harm the micro by the way... strange that firing a micro down a hall doesn't harm them as it is.)
