ARIA examples and Screen REader

Hello everyone,

I am looking for some examples of aria implementations which work with 
Screen Readers like JAWS V 10and Firefox v3. We would like to develop a 
new website here in the office and would like to incorporate some of the 
new technologies but in a way that blind and visually impaired people 
can access it.
If someone could send me some examples or links where to find some stuff 
I would really appriciate that.
I am looking especially for live regions and toolbars - if they work at 
all.

Thanks in advance for your help!

Kind regards

     Ginger
