--- Comment #9 from Léonie Watson <tink@tink.co.uk> ---
To confirm/extend Steve's findings...

The checked/unchecked state is accessibility supported in Chrome, Firefox, IE
and Safari. The indeterminate state is exposed in Chrome and
Firefox, but not IE or Safari.

Jaws and NVDA announce all three states correctly in Chrome and Firefox on
Windows. Window-Eyes announces all three states correctly in Firefox and IE
on Windows.

VoiceOver announces the checked/unchecked states correctly in Safari on OS X
and iOS, but not the indeterminate state. TalkBack announces the
checked/unchecked
states correctly in Chrome on Android, but not the indeterminate state.

Test cases and notes available here:
http://ljwatson.github.io/test-cases/checked-state/checked.html

Information about state seems to be natively available for the taking. I'm not
sure there is anything we should be doing except filing bugs with browser and
assistive tech vendors?
