You're welcome, @cairi.

My guess is, someone, somewhere, will come up with a way of doing it. It might take a while, who knows, but if Amazon and self-publishing is any indication as to the number of authors out there still writing book-length, manuscripts, it's in demand, and because it is, someone will find a way to make it work on the blockchain. If I had any coding skills whatsoever, I'd give it a try, simply because I'd want to use it.

In the meantime, though, there's other ways to let our creativity flow. :)
