Co-op uses internal Unity P2P networking. In layman terms, that means that a client becomes a server. Minecraft has a LAN/Singleplayer internalized server that runs on the client. Think of it like that, but with Raknet's NAT punchthrough, allowing you to run it over the Internet with minimal intervention. I provided a simple demo to help you get started on the LNA wiki. Be sure to change the values from LNA's information. You should be able to network players in a scene with that. It is incomplete though, and you'll probably want to modify it.
