Yes, it is possible, I do it, but not as good as I would like. You could read a book in twenty minutes as if it was a video with better comprehension that reading it slowly(as most of the brain disconnects with such a low bandwidth). When you speed read you train your eyes to look over a wide area and you are able to read several lines at the same time and train the brain to make sense of it(use the subconscious to store-order the lines automatically). So the best thing you could do is to control the formatting, so text is always the same size and always organized the same way, so if you force your brain to make sense of it, it does after time. The best structure is newspaper-like text, lots of columns, small lines so your brain could make sense of entire sentences with just an eye shot. It does not work with Hacker News, or most of the web by the way as each format is different and content is scrolled, with wide lines, not paginated. It works really well when you could control the formatting, aka non DRM text you could interpret with your own software, but if you try to sell this software you will have problems when even blind people are not permitted to modify copyrighted text.
