Later this month Sony will begin limiting the number of PS3s and PSPs that can share a game purchased through the Playstation Network, the UK Playstation blog said this morning.
It's unclear if the same restrictions will apply to Australian content and Playstation Network users as well.
Starting with game content purchased after November 18, a new policy will apply that limits the number of devices that the content can be "activated" on. Users will be able to play the game on no more than two activated PS3 systems. PSP owners will be able to play the game on no more than two activated portables.
This update will not affect game content purchased before November 18, but it will impact everything purchased after even for old PSPs and the PSPgo, they said.
