The peer relay approach is interesting because it essentially turns every node in your tailnet into a potential relay for other nodes. This is a meaningful architectural shift from relying on Tailscale's centralized DERP servers.

For anyone worried about the "rug pull" concern raised in another comment — this actually makes me more optimistic, not less. By distributing relay infrastructure to the edges, Tailscale is reducing its own operational cost per user while improving performance. That's the kind of flywheel that makes a generous free tier more sustainable, not less. Each new node potentially helps the whole network.
