I have an idea for an graphic novel navigated via handheld device that incorporates Stephen King’s 2000 e-book The Plant. For me to do what I would like to do and not infringe on copyright, I would either need a license with King or for him release into the creative commons.

I think the creative commons is the better route, maybe through a buyout like Blender did with NaN. With a new interface and new look, maybe The Plant could be revived (so to speak). The question, in that case, is how much should Stephen King get for his work done to date?
