Recently I ran into this idea of ad hoc wireless peer to peer networking. The idea being that anybody and everybody can instantaneously create an ad hoc wireless network simply by being within proximity to each other. Everyone knows about everyone and everybody is a friend with everybody else.

Sounds rather Utopian but from a real world perspective this is completely possible given the right equipment, authorization, authentication, and most of all, the right software.

I'm curious to see/find out what would happen if this type of networking actually took off and how people would use it. Imagine being able to share, discover, and basically network with anyone with whom you choose. What would you do with it?
