FWIW, there are definitely folks at Apple evangelizing about physical access issues within the company -- at the UMB event I'm at today, Jon Landis, a chem professor who now works for Apple, spent a couple of minutes on an aside kvelling about how the education division helped drive Apple's requirement that all of their laptops be opening with one finger or one point of contact.

That said, they've really spent much more time focusing on the BVI range of accessibility issues than ones revolving around non-mouse access. It's helped make the mobile side amazing, but I'd love to see accessibility tools on the computers beyond Voiceover.

Thanks for this post, btw (and the follow) -- it's going in the ever-growing list of toolkit things to keep in mind.
