This library is fully compatible with Flash Player 10, which requires that the clipboard copy operation be initiated by a user click event inside the Flash movie. This is achieved by automatically floating the invisible movie on top of a DOM element of your choice. Standard mouse events are even propagated out to your DOM element, so you can still have rollover and mouse down effects.
So in other words, zero clipboard is a legitimate use of the clickjacking trick to cover an element with a transparent element that provides another functionality.
There are detailed instructions how to use the library on the homepage.
I don’t know about you, but somehow “copy to clipboard” buttons seem a bit redundant to me and by keeping this functionality working cause more security holes than usability benefits.
