AAcckk!!

It's a LOGIC DEVICE, not a consumer appliance!!

Okay, so we can stop Microsoft from establishing that this kind of OS is
legally required on our machines, right?  *RIGHT??*

Microsoft's patent for a Digital Rights Management Operating System was
awarded yesterday:

  http://cryptome.org/ms-drm-os.htm

Abstract

A digital rights management operating system protects rights-managed
data, such as downloaded content, from access by untrusted programs
while the data is loaded into memory or on a page file as a result of
the execution of a trusted application that accesses the memory. To
protect the rights-managed data resident in memory, the digital rights
management operating system refuses to load an untrusted program into
memory while the trusted application is executing or removes the data
from memory before loading the untrusted program. If the untrusted
program executes at the operating system level, such as a debugger, the
digital rights management operating system renounces a trusted identity
created for it by the computer processor when the computer was booted.
To protect the rights-managed data on the page file, the digital rights
management operating system prohibits raw access to the page file, or
erases the data from the page file before allowing such access.
Alternatively, the digital rights management operating system can
encrypt the rights-managed data prior to writing it to the page file.
The digital rights management operating system also limits the functions
the user can perform on the rights-managed data and the trusted
application, and can provide a trusted clock used in place of the
standard computer clock.
