It would be REALLY useful to see who was where when receiving and sharing networked traffic, if only to get an idea of what area may be covered at any particular time, and by what variety of sharers. I can't understand why people are so shy of broadcasting their general whereabouts. We don't need to know the address, postcode and telephone number or what they had for breakfast - just the town or locality would do...
I, for instance, am about 60 nm south of Limoges in France (as the crow flies). I am in the hills, and because of the terrain can really only see the higher level traffic. If I knew that another user was, for example, on line in a more northern part of France, I know I'd have a better chance of seeing traffic descending into Limoges, which I can't do at the moment.
