Valve has just announced that a family sharing program will be going into effect and the beta will start next week. This beta will allow you to share your Steam games while earning your own Steam achievements and storing your own saves and application data to the Steam cloud. Once a device is authorized, the lender’s library of Steam games will be available for download and play. Unfortunately, when your friends / family are accessing a game you want to play, you can’t play the same game at the same time. However, the lender may always access and play their purchased games at any time. If you want to play a game that your friends is borrowing, they will be given a few minutes to either purchase the game or quit playing.
