I don't know the exact phrasing either. Also not sure if everybody wants to put their content under CC.

I think the government could make this messy enough to even foil the CC plan. For example they could set it up like GEMA for music - there would be an entity distributing the money and collecting it on behalf of the content providers. Besides, is there a standard way yet to announce CC content? That would be necessary to make it work for search engines.
