I'm not sure if you are right. See the safedisc patch created by Laurent 
Pinchart. In my opinion that code is completely legal. And it allows all 
programs with Safedisc 1.x protection to work.
When the patch was published, there was a discussion, and the conclusion was 
that the code is very probably legal, and is not against DMCA. But of course 
that should be checked with some lawyer.

So it could be done for one copy protection method, so maybe it can be done 
for others.

Are you sure about the above statements? Have you checked that, or it is just 
your opinion?

I can provide the safedisc patch against current cvs if anybody needs it.
