On the same machine, I mean.

I guess you could simulate this kind of thing with:

printf '[Interface]\nPrivateKey=%s\n' "$(wg genkey)" > conf
head -c $(( 33 * 10000 )) /dev/urandom | base64 | tr -d '\n' | fold -b -w 44 | sed -n 's/\(.*\)../[Peer]\nPublicKey=\1A=/p' >> conf
for i in {1..10000}; do ip link add wg$i type wireguard; wg setconf wg$i ./conf; done

Careful, though!

I've actually got something for this coming through the pipeline soon.
I'll keep the list posted when it's ready.
