The Printing Press brought us Copyright, the Internet brings... Usage Right!
I think creators now need to get paid for the USE of their work, not (just) for a copy. On the web, everything is a copy, every listen / watch / read / use is in fact a copy; computers are simply copy machines by default. If creators and rights-holders stick to the old definition of 'copy' and the corresponding, unit-based mode of how they used to get paid (e.g. the mechanical license for each download of a song), then we will continue to have a total mismatch between what 1.4 Billion Internet and the converging ~ 4 Billion mobile phone users are willing and / or able to pay, resulting in a drastic loss of revenues that could be harvested via revenue sharing, bundling and other collaborative, usage-based models.
