Honestly I'm highly doubting anyone would do so (release their plugin for free) because they're likely a profiteering gluten wanting to make a buck off it, but figured it'd be worth a shot.
I just wish Oxwall was creative commons - share alike, would make this tons easier and quicker and benefit the community here as a whole a lot better. As such were the case, I'd just release my generator into the wild without thinking twice about it.
