Develop a P2P overlay network to facilitate queries to a location regardless who is there
to provide the service.  Location-based query examples are:
	a) get me the average vehicle speed on 911 Pennsylvania Ave
	b) send me real-time images of the White House 
	c) show me "local" ads placed near Pennsylvania Ave and I Street corner

This project has to evaluate the feasibility of such an overlay network.  This should include
the development of the requirements for a) developing a location directory where the services
are registered and maintained.  Can such services be done without stationary (fixed location &
address) nodes? If yes, how would a query bootstraps into the location to obtain real IP addresses
for the service it needs?  If a totally ad hoc network formation cannot be maintained,
would the solution be like a hybrid P2P that have some Super peers that are stable?  Or do we rely
to a central (Napster) like directory as a meeting place?  Would this scale?

Dream queries:
	observe a car parked at a location; when it moves follow the car and report its position 
	all the restaurants
