Macrovision has released Cactus Data Shield 300.
To me it seems like the audio CD part hasn't changed much but the data CD part contains now DRM'ed wmas similar to files that are available in big music download stores.
If anyone's interested and doesn't care much about privacy: Here you can order an evaluation disk.
P.S.: Please no "Don't buy copy-protected CDs!" OT comments here. If you want to say something like that, feel free to ressurect one of the related threads or start a new one.
