I agree that the mere specter of liability can be enough to get corporations to do the right thing. One of my favorite Jim Thatcher quotes is that IBM long gave lip service to disability issues, but Section 508 made IBM take accessibility seriously. http://www.bestkungfu.com/archive/date/2004/08/web-accessibility-litigation/
Here's some RDF thinking for you: Why wasn't iLife 07 and iWork 07 announced at MacWorld? This is first omission of those products in at least three years, since iWork was introduced, longer for iLife. Is this not suspicious? I do not think there is a literal Accessibility Evangelist as a person, but I am hoping that perhaps the basic notion has been raised the level of fundamental internal requirement. (This fantasy is based entirely on Jobs mentioning voiceover at the past WWDC, I am grasping for straws here.) Apple has a strong reputation for not releasing products until they are ready. Maybe, just maybe, VoiceOver compatibility is one of the things holding up this year's release of iWork and iLife.
