You can use GPS as naming service (name collisions are then equivalent to
physical space collisions). You can actually label the nodes
automagically, once you know that it's a nearest-neighbour mesh spanned
over patches of Earth surface. You can use signal strenght and
relativistic ping to make mutual time of flight triangulation. It is a
good idea to use a few GPS anchor nodes, so that all domains are

No, an orthogonal identifier is sufficient. In fact, DNS loc would be a
The system can negotiate whatever routing method it uses. If the node
doesn't understand geographic routing, it falls back to legacy methods.
