Browser support status information request

Hi all, I'm a developer and i've heard about your work on the WAI-ARIA
standard, I found it helpfull for my new web site that necessary have to be
accessibile from people with disabilities, but I cannot find too much about
the level of adoption of this standard from the major browser (I mean
Firefox, Chrome, Internet Explorer, Opera, Safari) so I ask to you if you
have some information about that.


Thanks in advance for help.
