I don't have an answer to your question. I'm merely predicting (and I certainly could be wrong) how I see the concept of copyright being mooted by technology.
And IIRC, copyright is a relatively recent development in the history of human communications.
http://en.wikipedia.org/wiki/Copyright
The first copyright statute was the British Statute of Anne of 1709, the full title of which was: "An Act for the Encouragement of Learning, by vesting the Copies of Printed Books in the Authors or purchasers of such Copies, during the Times therein mentioned". Initially copyright only applied to published books, but over time copyright was extended to other uses, such as translations and derivative works.
Don’t look for the concept (intellectual property) to fade away very soon. Facebook is now trying (and is predicted to succeed) to get a patent on the word “face” (at least as far as websites are concerned).
A couple of years ago the Supreme Court declined to consider the case of Metabolite, which has the “right” to patent YOUR genes. For more on this see http://www.michaelcrichton.net/essay-nytimes-thisessaybreaksthelaw.html
The intellectual property maze is going to become a lot more confusing (read “ridiculous and unfair”) as time goes by.
Where there is money to be gain, fair play goes out the window.
