Is there a project that tries to build (using Raspberry Pis for example, or an app on a smartphone) a second global network of privately run nodes. The most similar project I can think of was the Fon project [1] where you would purchase a Fon box and share internet access with all other Fon users. Sort of an organised wifi hotspot club.
But, what I'm thinking about is more something that would just need electricity (vs electricity + ISP) and be running more like a big LAN. Everything would be P2P on it, from DNS to hosting. I think some federated systems could work almost just the same on it but possibilities (and speed) would be very limited.
With all the conflicts and natural disasters happening world wide I've been thinking more and more about ways to still be connected to others through something that would be more P2P even hardware wise.
I know internet (arpanet) started by trying to be just what I describe, but we all know now that it's not how it works anymore with some big centralisation points along the stack.
Is what I'm describing the "infamous" Web3? The few hazy definitions I read don't make it sound like it.
Anyways, if anybody knows any project that ressembles my poor explanation, I'm all ears as I'd like to get on board an promote it.
