If the method of viewing these isn't completely proprietary, someone should be setting up a site to distribute free and paid experiences. First or early to market would pay off like it did for early dominant Minecraft forums and the like. I can see this becoming a thing. As a commenter here notes, people could create graphic novels in 3D space.
