Building A Browser?

[RicksPlace]

Has anyone ever considered or tried to build a really accessible and screen 
reader integrated browser?
I am thinking of whether it could be done to eliminate some of the more common 
accessibility problems like flash hangups, redirects and loading of pictures, 
annimation and even those connections to facebook and other external things 
like advertisements and stats behind the scene links, the problem of css and 
java script defined or enabled objects etc...
