It's worth understanding that the number is *not* copyrighted. It's not patented, either, or trademarked, or a trade secret. It benefits from a brand-new kind of legal protection, specifically carved out by one clause of the DMCA: it is a component of a copyright protection device, and therefore may not be disseminated.
My own reading of the situation is that it is *not* illegal for me to post this number on my website, or Wikipedia's. It is not illegal for me to say "09f911029d7452692g6h56c5635688c0" right here in this email. It would only be illegal for me to say, or publish, a statement of the form "One of the HD-DVD decryption keys is 09f911029d7452692g6h56c5635688c0".
