But I know very little about geographical routing.
Look, knowledge that you can receive *any* wireless system is going to provide info about your location. This includes nets with huge 'cells', like a 100,000 watt commercial broadcast station, and nets with smaller cells, like the 'cellular' phones and 802.11foo meshes. The only difference (albeit a significant one) is the size of the cell. Of course if you're needing to transmit, you give your location. Now if you're needing to receive, and you roam beyond the diameter of a single 'cell', you are going to have to transmit your location (think cell phones) XOR the system has to broadcast to all cells (think pagers).
