If I understand correctly how these protections work, they rely heavily on multisession, which audio readers ignore altogether... So, I guess very old readers might work nicely... I remember my boss had an old creative cd reader with NO multisession support, quite annoying for data CDs, but this one might have been useful on protected audio... Unfortunately, I don't have access to it anymore, and I'm not going to buy anything from Celine Dion either ;-P
