I only have a little to offer: First, in college I knew a guy with RP. He was hands-down the most brilliant coder I knew at the time. Aside from blowing up the screen (screenreaders did not yet exist), he ended up simply memorizing his code. He held the whole thing in his head. I also knew -- internet-only -- a woman with the more severe form of Usher's (born deaf, go blind) -- who was quite techy even in the early 1990s and now works doing tech stuff for libraries, last I checked. She, also, had it going on. In short, I can tell you this: other people have done it, so you also have a shot at it.
