My buddy Jay from $work-- pointed me to the latest Vista EULA which is quite amusing (and a joke (I hope)):
Windows DRM: You may not use this system to remove DRM protection from Microsoft-provided media. "Removing DRM" is defined as stripping out protection, reverse-engineering code, using third-party circumvention software, installing non-DRM versions of DRM media, refusing to purchase our media in the first place, or reading Boing Boing.
