For home use only

Does anyone out there know if the “FOR HOME USE ONLY” clauses on some DVDs and video games are actually legally enforcable in Australia?

To me, it seems to be a form of EULA (end user license agreement) and the legality of those is untested in many places and questionably enforcable. If it is enforcable, it makes me wonder about stores that rent games or sell second-hand games. Do they need licenses to do that?

Do I need a license to lend a game to a friend? … hmmm… I think that I’ll write to Sony and ask for authorisation.
