Accessibility of Google+: Will Blind Users Be +1ing?

Interesting article. I tend to forget about accessibility issues on the web. I imagine something like Google+ or Facebook would be fairly difficult for blind users to navigate with so many asynchronous calls batting about.

On a somewhat unrelated note, are there any usability aids for smartphone users out there? Something like the Voiceover application mentioned in the article?

Edit: I'm mostly curious about Android phones.
