I would like to see this, and in fact, expected it to work like this. I mentioned this at dht-relay https://github.com/holepunchto/hyperswarm-dht-relay/issues/15#issue-1537472528 but didn't think to bring it up here. IT would be really nice to have a private network. Or, one person on the network has connection to internet, and the other doesn't, so the connection without can access the hyperswarm through that computer that does.

I'd be very keen on seeing this work, could we use multicast allow detection across LAN here to get the bootstrap done between lan hosts? Would that complete the circle for the holepunch process to work?

To cover my case i wrote some naive code:

every node send broadcasts every few seconds
every node listens on broadcast
if it happens there are two devices on the same LAN (home wifi router) they connect
