Aural captchas won't work for deaf people and for example the FreeBSD project has at least one deaf (as far as I know) superb programmer on board. And that's just a programmer, imagine your average userbase that wants to log a report. Visual captchas apparently require a high degree of colour variation to make it harder to be analyzed (http://sam.zoy.org/pwntcha/) which means people with a colour disability (http://www.w3.org/TR/turingtest/ http://en.wikipedia.org/wiki/Colorblindness).
