There's an interesting new video from the recent State of the Net Conference up on Public Knowledge, in which the RIAA's Cary Sherman discusses ISP content filtering and how it could easily be bested by encryption... unless they somehow find a way to have filters placed on end users computers to get around the "problem."

He goes on to suggest the filter could come as part of your anti-virus software, media player or P2P application, or even in an ISP-provided modem. I honestly don't see any of this happening given the consumer backlash it would provoke, but it's scary to think people actually come up with these ideas. Seems like instead of embracing new opportunities, the RIAA is willing to go great lengths to preserve their aging business model and protect their profits.
