I can't add too much here, but I think it is worth mentioning that, as I understand it, the algorithm for determining if a point lies within a polygon can be quite performance intensive: http://en.wikipedia.org/wiki/Point_in_polygon There are of course libraries for dealing with this problem, but I still think the performance question is still significant.
