still would detect massive gathering or people moving in bulk (in contrast to chance meetings staying near to each other) the math to do so isn't that hard...I could see how that could be useful to see in general how far apart people are in a crowd. As for how far one individual is from others, typical cellphone gps is only accurate to 10 feet or so I think, so that wouldn't work.
