That is a good point, and I do hope that more companies recognize that potential. I'm not an expert on the organization but from what I know they are based in Australia. They are well known for making
$1, which stands for Non Visual Desktop Access. NVDA is a screen reader and it is different others like Freedom Scientific's JAWS because it is free and open source. This allows the broader blind community that can't spend $1,000+ to have access to a screen reader. I haven't even bothered with JAWS because I like NVDA as it is. Anyways, that's about all I know about the organization, they have tons of information about the project and the story behind it on their site.
