The biggest risk that this company has is that Cloudflare (in all reality) should just buy them or reimplement it. It’s the type of product cloudflare would make, that’s for sure. Being based on open source wireguard, and being just a STUN/TURN server at its core… I’m sure that Tailscale will be the first but maybe not the best.
I’ve been dreaming lately of a tor-like network that’s based loosely on the idea of tailnets. Rather than blockchain bullshit, you’d have a direct ring of trust with friends, and then you could set up access policies to forward packets for people you don’t trust, but who know someone you do trust.
Web3 happens when people can host stuff on their phones, and Tailscale is something that lets you host things on your phone.
