Restricted CDs Quietly Distributed

fantazem writes: "I was just browsing news.com and found this rather interesting article just posted. The article basically explains that Macrovision along with unnamed labels have released thousands of CD's with a new form of copy protection." This is a follow-up to this article. Whitfield Diffie noted that the identity of the restricted CDs can be ascertained by polling a large enough sample of CD-buyers; a good way to avoid these defective products. Anybody bought one yet?
