Well, one nice thing about this plugin is it could be packaged with a single "story" that is a walkthrough on how to use it (or one for users, and one for writers). So if there's something you want to do that is slightly complicated, that might be a way of dealing with the issue.
I like the idea of copy/paste for the simplicity & safety, but I'm not sure if that will stop people from creating executable (I just really don't know). If that's going to be an issue, perhaps a single executable posted to Cnet, that adds any stories placed in a certain file might be an option. You guys would know the issues better than me though.
