Week two of CreativeCommons in Review, Lessig writes on interoperability, Digital Right Management and the Creative Commons license.

So how would Creative Commons licenses help with this problem? Our view is that they would help restore some balance between both extremes. We believed that if we provided a simple way for creators to say what freedoms they intend their content to carry, that would, for many creators, be enough. Not enough for Hollywood releasing a new film, perhaps. But enough for the widest range of creators who are making accessible their creative work through the Net.
