This document looks purely at the cost of the technical portions of Vista's content protection [Note B]. The political issues (under the heading of DRM) have been examined in exhaustive detail elsewhere and won't be commented on further, unless it's relevant to the cost analysis. However, one important point that must be kept in mind when reading this document is that in order to work, Vista's content protection must be able to violate the laws of physics, something that's unlikely to happen no matter how much the content industry wishes that it were possible [Note C].
Nicely put together article that avoids preaching most of the dogma around DRM.
