You don't need to be the NSA to break that type of encryption.
Consider distributed computing projects such the world community grid for a moment and the type of processing power technology like that can start to muster.
Would 1000 people be willing to help break an encryption scheme such as AACS if processor power was needed? How about 10,000? 100,000?
How much in computing resources is needed? I'll say you could have anywhere from between 1500GHz to 300,000GHz available to the right project.
Another consideration is that the type of encryption you're referring to is typically used to encrypt communications over an insecure connection between two secure locations. Since we (hardware owners) control both locations that are communicating and the connection between them it will only be a matter of time no matter what happens.
