Beginning in 2010, Blu-ray players must be configured to allow one full-resolution copy. Dubbed “managed copy,” the requirement has long been planned for the Blu-ray format, but has only just been finalized by the Advanced Access Content System License Administrator, a consortium of studios, hardware manufacturers and technology companies that licenses the AACS copy protection used on Blu-ray Discs. Managed copies can be made to recordable Blu-ray or DVD discs, as a download to a Windows Media DRM-compatible portable player or hard drive. Unfortunately none of the current batch of Blu-ray players or recorders have the required electronics to allow this. Manufacturers aren't expected to have this feature added to players until mid-2010.
Anyone know how AACS licensing might affect this being a firmware update in the future?
In any case, the language above (if true and accurate) seems to indicate that storage on media servers would be a possibility.
