This was my first thought as well. I wonder if what they refer to as the control plane[0] could be a DHT that contains keys instead. But as I thought more, I wonder what benefit a VPN-based fabric for P2P would have over protocol/application-level encrypted content. Granted the NAT busting features can help on their own, but otherwise I struggle to see the benefit assuming the protocol has encryption and P2P built in (I am probably just missing something). 0 - https://tailscale.com/blog/how-tailscale-works/ https://tailscale.com/blog/how-tailscale-works/
