Question:

Does the use of MPEG-21 DRM prevent the usage of superdistribution in AXMEDIS ?

Answer:

NO, absolutely not. AXMEDIS FulLY support superdistribution. With AXMEDIS you can distribute and share protected objects via P2P, the single objects are not protected for the single user, in general. On the other hand, with AXMEDIS tools, you can even reach that precision in protecting object. You can create a distinct object with a distinct protection for each user specifically for its license, etc.
