Anyone know about supposedly free software DRM?

Does anyone know how the supposedly free software DRM systems work?

My reading so far is that OpenIPMP is the only such project that has
produced a releasable product, but nothing on their website or on the
sourceforge forums says how it works.  There's lots of talk about the Java,
RSA, etc. technologies, but nothing about how they can give someone free
software and prevent all the users from viewing the same media with versions
modified to disable the rights-checking step.

The OpenIPMP website talks a lot about "reducing piracy" being their goal,
so how can they be trying to do that with a free software DRM system?

Are they distributing the software and using the EUCD/DMCA to say that it is
illegal to distribute the software if the rights-checking system is

Any info or pointers appreciated, ta.
