For discussions sake, let's say my books bring in $100 a month today. As a self published author, I keep 100 percent of my royalties. I take 10 percent, and create 10 shares, offering each for sale for $100 a piece, each entitling its owner to 1 percent of my future monthly royalty payments for as long as they own the share. Right now each would be paying a monthly royalty of 1 dollar, assuming my sales stayed at the same level, more or less. As my stock as a writer grows, and I get more sales, those shares pay more, and maybe the original buyer resells them to someone else for more than they bought them for.

I think there is a market for it. I'd sell some of my future royalties for some cash to live on while I grow my author platform. I think a lot of authors would.
