Yes, but how will they phrase the requirements? A CD is a single key (in fact 1,000 CD's are all part of a single key)... this leads to the same problem I heard of here a few years ago w.r.t. outlawing gangs: "It would be impossible to word any comprehensive anti-gang legislation in a manner which didn't also outlaw the police". The same goes for certain aspects of escrowing, any escrow rules which are in any way practical and useable will also be open to all sorts of creative interpretation ("You must deposit a copy of your encryption key with the government" -> "Here's the key. Where can I park the forklift that moves the container of CD's?"). Peter.
