Hoping to use this to reboot an ancient abandoned project. At the time there wasn't a mature P2P connection layer that took care of all the realities of the modern Internet out of the box. Now there is, and it's great to see.

This isn't Tailscale because it does secure P2P connections between any pair of devices, whether or not they have Tailscale. This enables real end-user P2P for, e.g., local-first apps with no server infrastructure except relays for resilience. And even if you lose the relay servers, things keep on working the same for any hosts that don't need them.
