Telltale Weekly (http://www.telltaleweekly.org/)
These people, are planning on making, and selling, audiobooks. When they make a certain amount of money, or a certain amount of copys are sold, they plan on making them public domain(I saw the exact numbers, but I forget them, and can't manage to find them now). I think it's an interesting idea, what does everyone else think?
