P2P, Mesh Network

  • going to be based on 802.11s (ESS Mesh) (which isn't done yet)

  • how do you do Digital Identity?

    • how do you authenticate messages sent over P2P as coming from a specific human?
  • each machine will run a Python-based Desktop Web Server to serve local WebApp-s, so writing for local use vs remote interaction is blurred - excellent.

  • need EMail (or other store-and-forward messaging) for communicating with people not connectible at the moment.

    • do you broadcast copies of outgoing messages to everyone, then have some way of deduping for the recipient, and aging/discarding for the other copies that end up sitting around undelivered on other machines? (this way a message eventually "finds" its recipient)

    • or maybe an explicit forward-via-intermediary approach: have a Village Server (which might not even have its own Always On connection to the outer Internet), and your friend can say "hey I'm going in to the village, do you want to give me some messages to pass along to the server?"

  • Instant Messaging and Presence Detection raises [its](http://wiki.laptop.org/go/Sugar Presence Refactor) own issues on top of this. I hope they don't try to reinvent SMTP on top of Jabber (though, actually, using the SMTP protocol on top of XMPP might be more defensible).
