Here is some initial feedback: Nice selection of static binaries!

However the choice to hardcode Google as a default STUN server is off-putting. IMHO, 2008's n2n would never set a third party server as a default. https://luca.ntop.org/n2n.pdf

Thanks for your feedback! Is there a publicly hosted STUN server that guarantees better privacy? I'd love to use it if there is an alternative. It is of course possible to use any other STUN/TURN server by changing the `--ice` flag and host your own with i.e. `coturn` ^^

Two users don't need to use the same STUN server in order for udp hole punching to worj, so choosing randomly from a list might be a good way to go.

There is work for using libp2p instead of a fixed third-party server:

One of the beautiful things about n2n was that the supernode program is relatively small and simple. (n2n does not require the use of STUN or TURN.) There is no need for a third party to be the one running the supernode/STUN/TURN server software. Users can run it themselves.

Just because home users must involve commercial third parties, e.g., ISP, cloud hosting, etc., in order to listen on globally reachable IP addresses does not also mean that users must also let those third parties have control over the software users run from those addresses.

n2n is neat! It is super simple to self-host the signaler in STUN/TURN in the case of weron as well: https://github.com/pojntfx/weron#1-start-a-signaling-server-... and `coturn` is even vendored through the Debian repos nowadays.

There is a very neat implementation of a TURN from Pion
