Thanks, Paul.

The problem with using down arrow with QuickNav off or Tab, in this
instance, is that this only moves between links and skips over
non-focusable elements. The purpose of the mega menu pattern, as used
here, is that you want to make other structured content besides the
menu links available, for instance, headings or textual cues. That
content is skipped using these navigation methods, at least,
apparently, with how I have VoiceOver set up.

As to the ARIA Authoring Practices, while those are valuable, if your
are doing something application-like, if you are using menus in the
way commonly found on web pages, you would likely violate many users
expectations by following the spec. As others have noted, web
applications--not to mention regular web sites that make sporadic use
of custom controls--are not the same as desktop applications. That
being said, mapping to system APIs does provide value. It is a
difficult nut to crack.
