VoiceOver on Mac OS X already does this. @title is exposed as AXHelp in the AX API, and by default, VO will speak the element's text equivalent label, pause, then speak "This item has a help tag." A user can have VoiceOver speak the help text using the VO+Shift+H hot key (a.k.a. Control+Option+Shift+H) or the user can configure VoiceOver to speak the help tag automatically: see VoiceOver Utility > Verbosity > Hints.

VoiceOver can also be used to show the native tooltip: see VoiceOver Utility > Navigation > Mouse cursor follows VoiceOver cursor. In this case, the mouse pointer follows the screen reader focus around, so the native mouse hover event is triggered and the tooltip is shown. 

Cheers.

PS. Steve, I'm not subbed to the HTML list, so if you want this reply posted there, you'll need to forward it or reply all. I included it for the sake of any later reply-alls, but my message is going to bounce from that list.
