Bootstrap phase. Do we rely on a well-known server listed in DNS to find or form an overlay,  or can it be entirely accomplished with something like bonjour?

With  a P2P communications architecture it might be possible to discover that people in the local broadcast domain want to hook up. Or to discover that they are injured and require emergency assistance, or that they are fellow emergency responders trying to organize a response.
