So this is somewhat similar to Iroh? https://github.com/n0-computer/iroh

In particular: https://github.com/n0-computer/dumbpipe https://github.com/cablehead/pai-sho

https://github.com/n0-computer/pigeons offers the same but with SSH. I use it in my homelab extensivelly for access, tunneling smb, postgres and some other minor bits.

This is smart. It's Magic Wormhole but for generalized connectivity, not just file transfer.

Yes, though MW has the important distinction that it uses short human-readable session identifiers. This means MW supports file transfer where the out-of-band channel is just a phone call. This is also why it needs PAKE as opposed to the simpler cryptography used in tailcat

Looks dope, though I'm surprised, is Tailscale fine with their DERP servers being used by non-customers like this? (Yes, it's a Tailscale project, but doesn't require login.) I vaguely assumed there was an auth step before you could use one as a relay. They mention a rate limit, but still

Tool like this exposes big problem with the current shape of the Internet, I believe.

Everything should be possible with just plain netcat and IP stack. Someone asks about NAT holepunching, encryption, static IDs, permissions, etc., yes this is what Internet lacks and why every P2P app reinvents it over and over again.

Repo suggests that they're running their own (rate-limited) DERP servers.

edit:

Which are probably tailscale's, as it's under tailscale/ github org?
