Wow I had not heard of this. Thank you for sharing. It says lighthouses are optional but recommended. Any idea how it can work without a lighthouse?

Haven't used, but I believe lighthouses are primarily for host discovery (dns) + hole punching. I think if you configure static hosts on all nodes you're good:

That's correct.
