It is a start though, Copy protection for PC games has not worked for years and years, only now are we starting to see protections that cannot be broken instantly (latest starforce for example hasn't been broken, only complex workarounds are around). Im sure someone will eventally get around it, but there are games that have been out for months and no crack as such has been released
I think the same will eventually happen with music, so as a concept i fully support it. Especially if it gets integrated to vista, should make life alot easier.
