[Feature request] Peer-to-peer connectivity option

So, when you launch the game with the mod installed, it says in the top-right corner "Connected to Service", therefore some kind of server must be involved in hosting the matches.

It's obviously nice that you provide this server to the players for free, but it would also be nice to have an option for P2P connection (or even offline LAN) as a fallback for the times when the server will no longer be supported or the connection to the server is blocked in some regions. I'm not that into the technical stuff, but I guess you already have open-sourced the networking stuff for people to setup their own servers.

However, hosting a private server is only half of the problem — players would also have to change some code in the files of the multiplayer mod to make it connect to the said private server. What if there was an option in the settings, like, "What server to use?" and then you could choose between either the official one or type in a custom IP:port?
