this is taken from Toms Hardware (Blu-ray link) One part of the announcement that had been anticipated by experts was Blu-ray's embrace of Advanced Access Content System (AACS), one version of which has also been adopted by the HD DVD Forum. This controversial technology would require that disc players maintain permanent connections to content providers via the Internet, making it possible for discs that fail a security check to trigger a notification process, enabling the provider to send the player a sort of "self-destruct code." This code would come in the form of a flash ROM "update" that would actually render the player useless, perhaps unless and until it is taken to a repair shop for reprogramming. The Blu-ray statement noted that certain elements of AACS have yet to be formally approved by the BDA. Who are they do disable/damage or interfere with the property of consumers!!?? Sony really cheese me off - and what of consumers who dont want/have an always on connection?
