Is it possible to use Ethernet or LAN to allow two players with Steam Family Sharing to play at the same time? I'm asking that because I saw a comment posted by @s1h4d0w to this answer by @S.Wessels:
S.Wessels: Two people are actually able to play at the same time. I've done this myself before, and as far as I can tell, Steam has done nothing to block this.
[…] If you both share a game on Steam, then both of you download the game. If one of you goes into offline mode, you can play at the same time. This obviously blocks online features such as saving to the cloud and online gameplay, but considering Skyrim is single-player (without mods), it shouldn't be a problem. This will also not work with games that are DRM, which require you to be online to start playing.
s1h4d0w: This is how me and the girlfriend do it. It blocks online features but we were still able to play Borderlands 2 co-op by connecting my PC and her laptop with an ethernet cable.
And I would like to know if it's true, and if it is, I would appreciate knowing the steps to do so.
