I am the author of several of CC-licensed music books including The How and the Tao of Old Time Banjo, A Book of Five Strings and The How and the Tao of Folk Guitar.Link
The Creative Commons concept has worked pretty well for us in terms of book sales over the last three years so I have decided to make my services as a music teach available under the same concept. I have posted a .pdf file on my blog stating that I am available for lessons or workshops on an expenses-only basis.
Right now there are groups in the UK and Australia working on setting up workshops - but I'm also hoping that we'll get some gigs closer to home.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
