They're coming out with consumer CD writers, that act basically like
a tape recorder -- they record audio in real time.  The more expensive
blanks are supposed to be surcharged by some amount that goes back to
artists whose work is being duplicated.

If you check on the web there's a simple hack to the consumer machines
such that you put in a 'audio' CD blank, let it spin up, then get the door
open without triggering the disk change sensor, and put in a regular
'Data' blank.

The restrictions on media do not apply to any computer-connected CDR
burner to my knowledge.
