Thanks to everyone (especially Tim) for your feedback on this. Gez Lemon has updated the article to include Voiceover: http://juicystudio.com/article/screen-reader-mouseover.php#voiceover
They will be following up later with other JavaScript events, for which I'll help to provide the results for Voiceover, hopefully with some help from the list again :) Kind regards, -Alastair
