bool2 (1782642) writes "A soon to be implemented DRM scheme, UltraViolet, is a joint effort between companies such as Sony, Adobe, Cisco, HP, Microsoft and Intel. What seperates UltraViolet apart from other types of DRM is its use of "the cloud." Whereas most other DRM schemes are implemented locally, UltraViolet intends to store the digital media you purchase on a centralized server with the goal of preventing users from storing their digital media on unauthorized devices, sharing and making copies.
More general information can be found at the Ultraviolet website"
