Ridiculous. I’d imagine all that the disabled would ever need already exists in the form of talking browsers with speech synthesizers. They are only limited by the equipment and software/browsers they purchase and use at home. Indeed, everything about the internet is already ideally existing for the disabled compared to brick-n-mortar stores.
However, the big problem on almost all websites is COLOR, and that covers only government websites. Presumably the color blind, or deficient (all the dudes using viagra are losing blue btw) will know how to ADJUST things so that they can see all the characters one way or the other.
