Main downside I see compared to DERP is there's no way for this to work in the browser since it's native UDP. I wonder if it'd be possible to make it work over WebTransport in the future.

(Tailscalar) I'm very bullish on WebTransport in the future, but, it doesn't solve for NAT traversal. I'm watching keenly as well how Iroh gets on with QAD, relatedly.

If it all comes together this may well become more magic :D

But this is specifically for relays, so you shouldn't need NAT traversal right? ie in the browser you already know p2p isn't going to work (unless Tailscale implements WebRTC support) so you just go straight to relays for everything.

I hadn't heard about iroh using QAD. Thanks for that.

True, the relays currently use http and have a web socket path. The web based ssh client in the admin panel uses this transport.
