There's something about DRM that makes people stupid. Content providers believe it will give them total control over customers. They drool over anything that has "DRM" in its name until they can't see it clearly. Then they spend their billions on something any competent engineer could out-design and out-code in two months.
How else can you explain ideas like Aladdin's recent
US patent application for an "XCD"? (
story,
slashdot story.) This is an encrypted CD or DVD, with one edge shaped into a USB contact. The USB gives access to a key that lets a special player application access the data on the disc itself.
