If I'm not mistaken, you are free to do with the code as you wish, other then use it elsewhere or on multiple UNA scripts without paying for those in use licenses, and backward engineer it. from what I understand. But not completely sure on that.
Sorry if my post came off as you not being able to modify the code, wasn't my intent to convey that. I meant sharing of the module overall, even if it meant sharing with a new maintainer.
