Honestly, every time I hear people talking about doing away with copyright and coming up with "alternative models", I keep thinking of the 60's hippies who said we'd all live in communes and take LSD regularly, and that it was a "revolution" that the US would soon adapt. That never ended up happening.
I think people are starting to see the downside of turning writing into a commodity rather than a product. We're starting to see that people are too cheap to pay when you do a "pay what you think is fair" for record downloads. I think 4e's OGL revision shows this trend.
What will probably end up happening is some content providers will go out of business, and those "alternative providers" will end up finding out that once they are out of high school and college, they won't be able to devote time to working on their hobby. You'll probably see attitudes change once this starts happening.
