The broader concept of virtualizing networks has existed forever: the Virtual Private Network. New protocols make VPNs better than before, WireGuard is pioneering easy and efficient tunneling between peers. Marry the VPN to identity, and make it work anywhere, and you can have a virtual 90s-style LAN made up of all your 21st century devices. Let the internet be the dumb pipe, let your endpoints determine who they will talk to based on the person at the other end.
