aDesigner: See how your site looks with a visual impairment

aDesigner is a Java based tool from lBM’s alphaWorks, that lets designers and developers see how their site looks and sounds to a person with low-vision impairment or blindness. But how horrible to design a tool using Java and only release it for Windows 2000 and XP. I am going to try using this tool in a presentation to management to get additional support for accessibility efforts.
