I've used wormhole once to move a 70 GB file. Couldn't possibly do that before. And yes, I know I used the bandwidth of the relay server, I donated to Debian immediately afterwards (they run the relay for the version in the apt package).

It took this far down in the comments to get to some inkling of the meat of this.

It relys on some singular or small set of donated servers?

NAT <-> NAT traversal is obviously the biggest motivator, since otherwise you just scp or rsync or sftp if you don't have the dual barrier.

Is the relay server configurable? Seemed to be implied it is somewhat hardcoded.

All of them require an account on the other machine and aren't really suitable for quick transfer one-off file transfer from one computer to another that you don't own.

If I have a direct network connection I tend to go with:

    python3 -m http.server
or

    tar ...| nc
Neither of which is great, but at least you'll find them on many machines already preinstalled.
