It has been shown that criminalizing isn't working. Reward might, and it is worth a try.
Another proposition for Sony would be to reward their customers rather then criminalizing them. Maybe by providing some way to VOLUNTARILY register a CD with Sony, you could get 5 free downloads from their music store in a DRM (or beter yet, non-DRM format) or earn points to get other merchadise from Sony similar to the Sony Rewards credit card program. It's been proven that reward works over punishment. I'm sure there are some kinks that would have to be worked out, but I think Sony should give it a try.
