Thanks to Joe for forwarding this interesting message from security
expert Peter Gutmann about an issue that affects far more than
just Windows users.

This document is not light reading, but well worth looking at. It
shows the many technical drawbacks caused by implementing Digital
Rights Management in general purpose computers.


Executive Summary

Windows Vista includes an extensive reworking of core OS elements in order to
provide content protection for so-called "premium content", typically HD data
from Blu-Ray and HD-DVD sources.  Providing this protection incurs
considerable costs in terms of system performance, system stability, 
support overhead, and hardware and software cost.  These issues affect not
only users of Vista but the entire PC industry, since the effects of the
protection measures extend to cover all hardware and software that will ever
come into contact with Vista, even if it's not used directly with Vista (for
example hardware in a Macintosh computer or on a Linux server).  This 
analyses the cost involved in Vista's content protection, and the collateral
damage that this incurs throughout the computer industry.
