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 disabled?
Any info or pointers appreciated, ta.
