I would have to see a demo but i doubt it. I think my biggest concern is that it would really have to be timed right so i am not waitimg for the next word. The way i read is also sometimes scanning depending on how interesting or important the current section and also I sometimes like to go back and scan a paragraph to add context to something i just read. I guess what i am saying is it seems too restrictive. But i would be interested seeing it in action.
