I think Kynn has clearly identifed what could be a good path for solving these problems, and equally clearly identifed the largest obstacle to success using that path.

When dealing with users with different needs and those with multiple needs, there are some cases in which it might indeed be good to say "this is a type of presentation that -best benefits users who are blind-" or "this is how you can make a site more accessible -for users who have learning disabilities-". Many of these techniques may prove to be very powerful and useful, and with evolving technologies that enable server-side transformations of the user experience, we can't just discard a solution that works for one audience because it doesn't fit in our model of "single source universal design." Jonathan's various demonstrations are good examples of this. Most all of what he's presented as possible (partial?) solutions for users with cognitive impairments are highly inaccessible to users who are visually impaired. However, if we consider the option of delivering custom, personalized user interfaces, then we find a way to use some of the suggestions made here that aren't compatible with single source design. Jonathan's idea works for learning disabled users but not for people without vision? Great! We'll add it to our toolbox called "optimizing sites for people with learning disabilities" and not our toolbox called "optimizing sites for people who are blind." --Kynn PS: The catch, of course, is to do this selection/optimization in an accurate, inclusive, and "correct" way. And that's not easy to do reliably -- it takes a lot of work and a lot of understanding of the issues, not to mention employing various protocols and technologies that have rarely been tied together in this way. By the way -- this is what we're working on at Edapta.
