>you can use such a feature to triangulate a location, I never thought of that.
Of course this is exactly what people are going to do with that kind of feature. Sharing of location data is such an obvious thing to get exploited. It is part of the human base instinct is to take any new thing to the worst places it can go. There are certain aspects that the first question should be how can this get exploited for uses other than how we want to use it. If nobody in the room can come up with a way, then you need different people in the room.
