Just wondering, if we use the technique above, how do we determine what item the button was clicked on?

To answer Brian's question, in the button click handler you can walk up the visual tree to find the item that contains the button:

        DependencyObject dep = (DependencyObject)e.OriginalSource;
        while ((dep != null) && !(dep is ListBoxItem))
        {
            dep = VisualTreeHelper.GetParent(dep);
        }

        if (dep != null)
        {
            // TODO: do stuff with the item here.
        }
