Two years of architecture and design, months of coding, loads of money. And finally what do we have ? A security mechanism that can be defeated by just a tiny piece of opaque tape and causing the biggest media catastrophe for Sony in the ten last years ! PA-THE-TIC !!!! As Tantek told me many years ago, "Always let the Music and Film Industries define their own protected formats, that's the best way to ensure it'll be copiable " :-)
