This is exactly it. For years Western governments have been worried that terrorists might build a secure distribution network for information and orders, and now Hollywood is building one. A fake record label would be a fantastic front for such a thing; each subscriber device (such as a PC or mobile phone) can be uniquely identified, so when your agent downloads the latest hit single he actually gets four minutes of orders etc; nobody can tell from the outside, it's wiretap-resistant, the agent can't have the key beaten out of him because he doesn't know it, it's difficult and time-consuming to extract it from the device, and because everyone has one it's quite hard to use traffic analysis alone to pick out suspects. There is no way Microsoft is going to build in a back door to Vista for Special Branch - once they do that for one government and it becomes known all hell breaks loose and they get banned from half their markets. Some form of crazy overcomplicated key escrow system might happen; might as well tie people's TCPA keys to their biometric identity cards, right?
