I'm thinking of doing up a couple of premium themes, and selling copies of them. I've never done anything like this before, so I have a couple of questions.
I appreciate that this is mainly a forum for asking technical questions, so if anyone wants to point me in the direction of somewhere that might be more appropriate for these questions, please let me know.
My main question is about copies of a theme. If I sell a copy of a premium theme, and the end result is that a person gets a zip file of my theme, is there any technical way to limit them to only using it in one installation of WordPress? Or do I just rely on the goodness of their hearts?
Also, a related question: What kind of license, if any, should I include with a premium theme?
