Nice to see this topic!

I agree with all Steve's points below, and add from personal  
experience watching blind users: we know tab order is important to  
most users -  but tab order and field labels are particularly  
important to blind users. I have watched blind users get quite irked  
when the tab order is illogical and/or field labels don't make sense  
to the purpose of the form.

I'd also add to stay away from  single-select drop-down lists that  
add additional fields on selection.  The form constantly changes as  
the user tries to make her/his way through the drop-down list -   
quite crazy-making for blind users when each element on the list is  
treated as a selection as it is read.

Absolutely-  it's important to not confuse needs with human  
behaviors. Blind users have special NEEDS, but still have the same  
range of behaviors as any other user. :-)
