As far as I know they haven't--YET. You can bet they've thought about all

Somebody made the point in an article on copy protection schemes for audio
media that most consumers who paid $17 for a CD at the mall expect to be
able to take it home and rip it. Pay extra for some crummy mp3's? HA!

The Music Industry can start impressing me by cutting the price of new CD's
in half...

SPDIF isn't a standard feature on the Mac. It would have to be a
third-party card.
