Hmm. I'm going to discuss this in the Web Content Guidelines group, becuase
it raises some interesting issues that I think that group should consider.

(In other words before I answer I'd like to toss his around a few other
people...)

  Charles,
  
  Thanks for the useful info.
  
  Expanding my question into an area where my knowledge is limited, is it
  possible to make pop-up menus that are generated by a mouseover accessible?
  An example is the main menu at http://webaim.org (accessibility note: though
  the pop-up menus on this page may not be directly accessible, an equivalent
  to the menus is provided in the form of a submenu on each page).  Is there a
  way to make the pop-up menu directly accessible so that an alternative
  (submenu) does not need to be provided?
  
  Thanks,
  Crystal Allen
