I really say everything about the renderer and copyright issues because a) I don't know how much you know about the details, and b) I don't know how much anyone else reading this knows about the details.
I'm not sure how the book in your library got updated, I have no code to do that and as far as I know I actually can't find the original book location without querying calibre's SQLite database. I had talked about doing it at one time, but Kovid (maybe davidfor?) pointed out that doing so would cause problems if anyone ever used a non-Kobo reader and uploaded the epubs. If you upload a book with my plugin and then save it to your library, I believe that would put the modified book into your library, not sure how else it could have happened. Maybe you added a book that had already been modified.
