gonna have to open the book and re-read it, I had understood that the gpl only really had two restrictions, 1)you must include a copy of the gpl in your release, and 2) you must make available a copy of the source code of the app. I know you can't go back from a gpl to an oem license ( why on earth would you want to rip yourself off of the millions of hours of free coding from the community by going oem I don't know )
