But if I understand it right, in that case the developer was distributing the app, signed with his own developer's account, abusing the 100 devices you have for testing. What I meant was to let the users be the developers, and sign and deploy it themselves. If you didn't care about selling it, you could just dump the source somewhere with a little installation script. I can imagine many IOS users who would like to use emulators or other banned apps would happily pay $99 and compile their own stuff.
