The new drm apparently allows for multiple encryption passes and per file keys.
How it gets implemented remains to be seen but the possibility of per-file encryption suggests you might need to authenticate each file individually every time it is downloaded to a device or ADE installation, not just when it is downloaded from the store to the PC. Layered encryption might require a live internet connection for authentication the first time a file is opened for reading.
Conceivably, a file might need three authentications with three different single-use keys to get it to open for the first time.

And all keys must be on the consumer's machine at some point.
Amazon's DRM generally uses a per-book and per-device encryption scheme. It doesn't seem to have helped.
I wonder if i<heart>cabbages relishes a new challenge?
