Future Unity 2D accessibility question

[Hammer Attila]

Hy,

Now I read following:
http://www.webupd8.org/2011/01/2d-unity-to-be-available-as-option-in.html
In Natty this is an optional possibility I think. When will be default 
this possibility? In 11.10?
The problem is Unity 2D using QT toolkit with is now not accessible. 
Luke, what can possible doing this situation? If a visual impaired user 
machine Compiz works only after installing proprietary graphics driver, 
before this task impossible to using Ubuntu because QT the toolkit?
