FYI:

But, how do they power it?

>From <http://www.doc-witness.com/>

  An OPSECURE PROTECTED CD looks like a
  regular CD but contains a smart card and
  optical input-output system...

  An OpSecure protected media does not
  only reflect stamped or burnt information
  but can also RECEIVE, STORE, PROCESS,
  and TRANSMIT INFORMATION....

  It is impracticable to
  crack since it is hardware based and is
  based on dynamic protection

Also mentioned but no further insight:
