Somebody started a petition today at no-dmca.ch. 50'000 will be very hard with no party and organisational support and little time left.

Contrary to the DMCA, downloading for noncommercial purposes will still be legal. Also the use of DRM circumvention tools for rights you have anyway stays legal. But the development and advertising for these programs will become illegal. This affects pretty much every DVD player software at least for Linux, because it has to break the CSS "encryption attempt".
