I can finally talk about this, 3 years later... github.com/tailscale/ta... It's a library + CLI tool that's like netcat, but over Tailscale's data plane without any control plane (no accounts, no dependence on Tailscale the company, all open source) WireGuard + NAT traversal without IP addresses.

I remember when wush came out and I saw the README I was like "ugh, we should release derpcat" (since renamed tailcat to not imply it's always over DERP) But I haven't used wush or seen how it works. I suspect approximately the same, though.
