Seems that most of what you hear in and about Second Life recently revolves around creator rights, copyrights, trademarks, intellectual property rights, infringement and so forth. It's not that intellectual property infringement is new – you can certainly replicate content with the official viewer if you know how – but it is in the limelight and a major feature of Second Life discussions by virtue of assorted high-profile infringements, and legal actions.
Copyright infringement can't be made to go away. Since the Statute of Anne in 1710 originally codified copyrights in law, infringement has only been somewhat quelled by various means, never practically eliminated. In these predominantly digital times, there are many new tradeoffs could be made that could reduce the incidence of infringement, but at the cost of also reducing functionality.
