The era of Trusted Computing?
Trusted Computing is arriving slowly but with firm steps to all computers. Trusted Platform Modules (TPM) are now embedded in many computers, and is expected that by 2008 most systems will be shipped with a TCG complient TPM.
While TPM 1.1, the current version shipped with many computers, is nothing more than a smartcard sitting in the LPC bus, the next TPM version promises many more features. The uses of trusted computing are many, including remote attestation, secure storage, and, yes, DRM. Some more interesting uses can be found here
