About Steam Family Sharing

Well, in theory probably you can - all you have to do is to login into steam client on your friends' computer and authorize family sharing. According to the FAQ it is possible to share you game library on up to 10 computers. However I have no any idea how steam will react on your accounts' "teleportation" between countries :D

hi at this stage of development you can use your friends complete library (without some special games) in your account. it doesn't matter where they live or if you use the same machine. But if you want to play at your library, your friend will be getting a message to exit the library within 5 minutes. that means only one persone can use a library at the same time.
