Make the most of your network. Get more play for your gamers. Download your games once and serve them out to many people at your LAN.
Had never seen this service before and randomly saw it in Unraid CA now. Thought I'd share this, as it seems like a very cool project, especially for those hosting LAN parties.
With newer versions of Steam, it's just handled automatically as long as you enable it, you can download from other players on the network. True not all games are on steam, and this probably works well for massive LAN setups, but I tried and failed to set this up, it's a bit of a pain and personally found it not worth the effort.
