I disagree. In the case of MIDI, or a printer it has significant non infringing uses, and they weren't implemented solely, and with great detailed knowledge of the work in question. If you had a printer that was designed specifically to print Steven King's It and wouldn't work with any other novel then you would have something parallel to what they have built. Their project isn't general, you couldn't use it to target a couple of open source games, or a couple of games you wrote yourself.
