Yeah, it’s good to think about what an ideal should be but the facts on the ground can seem a bit murkier. If you are in the US, my guess (and yeah, it’s a guess) is that you might be able to move around the “Non-Commercial” via Fair Use.http://en.wikipedia.org/wiki/Fair_use
1. the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes; 2. the nature of the copyrighted work; 3. the amount and substantiality of the portion used in relation to the copyrighted work as a whole; 4. and the effect of the use upon the potential market for or value of the copyrighted work.
Calling Mark Tribe…
Anyways, regardless of how one thinks about it, I am happy to see people like WGBH trying to get content into artist and activist hands (thanks Brian). Now, if you can copy left some old Bob Vila era This Old House, I might have art project for you.
