Correct, it didn't support SafeDisc 2. However I think that at least part of it was accepted. Anyway the reason that some part was not not accepted was not DMCA related.
What the DMCA says is bad enough however there is no reason to claim that the DMCA says thing that it doesn't.
Any implementation of SafeDisc in Wine would not be PRIMARILY designed as a circumvention device through any remotely reasonable definition of circumvention device and in addition to that PRIMARILY designed needs to be proven as well.
SafeDisc simply tries to assure that the CD in the drive is not a copy. Nothing more, nothing less.
Please people, don't let DMCA paranoia reach new heights.
