Section 508 "requires all Federal agencies to make electronic
and information technology accessible to people with disabilities".

A number of the challenge/response protocols proposed here (as well 
as those currently in use at Yahoo and other webmail sites, as well 
as at search engines like Google) contain tests whereby you look at 
an image containing non-ocr'able text (typically it's either 
distressed in some way, or has a weird background) and type in the 
text of the word you see.  This assures the sender/presenter that you 
are a human and not a robot trying to spam.  Those won't work if you 
are blind.  As a result I would assert that any challenge/response 
system that uses such a test will not be acceptable to the U.S. 
Government for use in government funded mail software.

I don't know if providing both visual and aural tests would be sufficient.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
