What I want is a meshnet like alt network. Something that can hop node to node and your personal devices are where your Facebook like page/blog is kept. Go to a con? People can log onto the net made from the gathering as boxes register with either other boxes or with a ‘checking’ box to get the shared token/cert ‘hey this is all one network’ or onto a person’s box and from there browse, offload stuff for them, or download things from them.
Think piratebox mixed with meshnet hosted on a raspberry pi like ultra portable box that has enough horsepower to be a network node hosting something like a mix of a WordPress blog/twitter/filehost.
