Have you made any progress? kendomixes has made a very good point in the post: "Manage time limits per person, not per device." I have the same problem. You have a serious issue here. If you intend to keep your product viable, this needs to be solved. I have devices all over the house rendering Norton Family totally useless if all my child has to do is pick up another one to start over again. That post is almost a year old. I hope you're working on this.
