One of the most brilliant coders I've ever worked with was 90% blind. He had a gigantic monitor, and his term setup was such that the gigantic screen showed big chars, 3 at a time. He'd scroll through code like lightning, reading it 1 or 2 chars at a time, and despite this limitation was one of the best kernel hackers of my professional experience. (We bonded as the only vi users in the dev group..)

To this day, I doubt I'd have the temerity and courage to work in this field as he did, and I have to say that I have immense respect for the disabled who overcome these disabilities and nevertheless remain extremely productive. It says something of a persons resolve that they are willing and able to write and debug kernel code, 1 char at a time .. I really don't think I could do it.
