Is there a jQuery plugin or JavaScript script that automagically loops through each CSS hover (found in an external stylesheet) and binds it with a double touchdown event?
If there isn't something like this yet, can it be made and how (guidelines)?
EDIT:
To be clear, I am not in search of a double tap. Touchdown 1 is a single tab just like Touchdown 2 is. There can be as less as 0 seconds between both or as much as 3 minutes, that's the user's choice.

... or check out the demo on my web site. Note that it's set up to only work its magic on the iPad - detecting all versions of the iOS is another question in my books ;)
It works on the basis of the fact that...
After you click a link on the iphone or ipad, it leaves a simulated mouse hover that triggers the a:hover css styling on that link. If the link has a javascript handler that keeps you on same page, the hover state will not change until you click on another link.

I've used this:
$(document).ready(function() {
$('.hover').bind('touchstart touchend', function(e) {
e.preventDefault();
$(this).toggleClass('hover_effect');
});
});
Before, to allow hover on certain elements. Obviously you'll need to tweak it for your own use, but it's a nice way to allow a touch and hold hover effect.

Here is a further optimized version that also handles closing the :hover
You'll have to encapsulate your site with a
<div id="container"></div>
for it to work. Just putting the closing event on the body did nothing
var bodyBound = false;
var container;
if (navigator.userAgent.match(/iPhone/i) || navigator.userAgent.match(/iPod/i) || navigator.userAgent.match(/iPad/i))
{
container = $("#container");
// Provoke iOS :hover event
$("a.someLink").on("mouseover", handleHoverClick);
}
function handleClose(event)
{
container.off("click", handleClose);
bodyBound = false;
}
function handleHoverClick(event)
{
if (!bodyBound)
{
bodyBound = true;
// Somehow, just calling this function—even if empty—closes the :hover
container.on("click", handleClose);
}
}
