Nebula mesh: a peer-to-peer VPN by Slack

This was previously linked (e.g. [0]), but it didn’t get any attention, so I reposted it with a ‘more interesting’ title.

Hope that’s acceptable, because I’m interested in learning more about this network architecture. Is a vpn mesh — if embedded in the client — a possible backbone of a truly server-less and decentraized/distributed social network?
