Accessibility is one of those things we the privileged (those with workable eyesight and hearing) tend to forget about; That's why developers like Debian's Samuel Thibault deserve great respect. The guy was brought to my attention by the great Raphael Hertzog through one of his all-important People Behind Debian series of interviews.

This is one of those things that make me wish I was rich... pay a bunch of people interested in this kind of work to do it full-time.
