I have a small problem. A friend of mine makes music and encodes the tracks onto mp3s. He also makes his own videos, but he's real paranoid. He was wondering if there's a way to make a disc read only, but not copiable. In other words, he wants to be able to show off his work, but is worried about people making copies of it. I told him, quite humorously, that if I knew of how to do such a thing, software developers would throw money at my feet. But I thought I'd throw it out there. Any ideas? The closest I could think of was to encrypt the data using a rotating password that could only be obtained thru a website I set up with an authentication script...kinda like a software implementation of a secureid, but first, I don't really know how to create a rotating password and second, once someone has the password, they have read access which means it is copiable.
