So, you thought that only Linux users (and other alternative OS zealots) would benefit from reverse engineered Windows drivers? Ha! Far from the truth, it's the Windows users themselves who are benefitting. (Sorry, that link is in German)
Too bad that this specific Windows port actually infringes my copyrights since it links my GPL'ed code against the non-free inpout32.dll. And the guy who did that port doesn't even think it's necessary to put his email address anywhere.
