One solution?
Perhaps I'm not expressing myself well enough, but I think the best solution is to implement a set of laws or rules that will provide an environment that will encourage creation and investment. That's what the intellectual property organizations' treaties were designed to do. When you see them implemented, you very clearly see a migration from illegal back to legal. One of the principal reasons you see this is that not only is there someone saying you can't do this, but all of a sudden there is an interest from investors in investing in that marketplace and developing legal alternatives that are attractive to the consumer.
It's like a carrot and a stick: you have to have great carrots--lots of alternatives.
