Take a look at Form.Observer -- it's ideal for this sort of thing. It
watches the form in a tight loop (at your specified interval) and if
there are any changes to the form from the last time, it fires a
function.

You might want to try adding an observer to all form elements to detect when
the values change. For example:
var isDirty = false;
$$('input, textarea').invoke('observe', 'change', function()
{
isDirty = true;
});
