sheet music.

sheet music attempted to stop records
records attempted to stop radio
...
Movie industry sued sony for the beta-max. All the way to today where RIA is suing Grandmothers over downloaded music. The same is true with books and copy machines. The idea of DRM has always lost in end to better tech and to what ever growing industry emerges.

I wish you well but there will always be someone you will dis-please with any attempts to use DRM.
