Hi Art,
Yes. Definitely something to think about now. If in the future the technology behind Bitcoin could be used to make an electronic (music) file a unique document with information about who created it, ownership, copyright, licensing and publisher info an intrinsic part of the file itself then every copy of it would be just that – a copy – an unlicensable, undocumented counterfeit – still able to be listened to presumably, but not exploited.
