Coincidently this [1] just come from one of my suppliers. Perhaps a wire mesh network, completely outside the normal Internet might be an answer. If the Internet moves to be fully IPV6 then IPV4 can easily be used with off-Internet networks, almost as needed, provided the current IPV4 space becomes otherwise worthless to the world via Internet (that is being talked about, dumping IPV4 completely and going entirely with IPV6 for the future, perhaps even in the near future, but who knows). Not sure the state of this network [2], but it might be interesting. And one day, if this ever becomes a solution [3], looks like a recent release -- it is just messaging though I think, which I do with my own XMPP (jabber) esrver. However, this one is client to client over Tor with no server in the middle, so it's beter. [1] http://www2.bluechipit.com.au/eMarketing/weeklySpecial/21.11.16/Cambium_E500...
