I"m not even sure what practical applications this would have given how ubiquitous smartphones are Yet it interests me.
Person A has a pi mounted in their car. Person B has one in their coat. Person C had one mounted in... say... a bus-stop shelter.
How do we get Pi's A and B talking to C without user interaction? What they do after is immaterial so far as I know since if you get a connection you could do all sorts of things 9check a folder/feed/whatever for updates, pull files, upload files. All this on the idea the connecting units can tell one user/connection from another.)
Right now could be a solution/concept without a problem but I like the idea, especially if you're suddenly in a situation where the internet itself isn't stable and you want to pass on metric boatloads of info (like a disaster-centric wiki, or simply syncing news/mail from person to person until it gets to a final destination.
How... un-practicle is this?
Edit: Friend had a good idea. Have personal widgets, but you'd have stationary objects that act as aggrigate/nodes and the foot traffic is what gets things from node to node.
What i'm stumped on is if, say, you sent a message to Pete how do we keep the message to pete from propagating Everywhere endlessly even after Pete's gotten it?
Then there's security both in making sure the id/tag/whatever telling your personal pi thing apart from everyone else isn't cloaned/copied. And then thre's 'how do you keep this from becoming a police state nightmare?
Yes i write. Yes this might be a short story. But right now i"m just looking at it as a logistics challange.
