The only area with fairly solid evidence on this form of dual-licensing is
software, and that's a different industry with a distinct set of
attributes. The key for us would be a good idea of derivative works and
copyleft licenses as they apply to text, images, or any other content we
might own.
There's anecdotal evidence for this happening for images. The
Wikimedia enquiry address gets a lot of requests to discuss licensing
for an image, generally assuming we're the copyright holder (but
sometimes asking directly for the author); money is certainly in the
air on some occasions, though I suspect most end up as "Sure, use it,
can you put my name on the flyleaf?"
