I was once part of an audio book venture that created a book reader app and and associated library application library that was specifically designed to be used by the blind and severely disabled. It actually met all its goals in regards to usability. So the company took it to the largest national organizations to get their seal of approval for it. The company was turned down by all of them because although application interface years ahead of any other application in regrades to the blind and severely disabled, their words, it did not accommodate the deaf. An audio book application that did not accommodate the deaf.
Sorry dude but your story sounds like an urban myth. I'm not buying it.
