All I've seen on this issue is a bunch of hysterics and very little concrete information. It smells like bullshit to me. The chances of a compulsory license scheme passing as a law are practically nonexistent as it would violate international copyright treaties. Plus, I'm a copyleft supporter. Copyright law is already a mess and too restrictive - the "Mickey Mouse Protection Act" copyright law is a good example. Anything that can change that is good as far as I'm concerned.
It's only the beginning. Check what Monsanto is doing with natural seeds.
