I know this is not the intended use for a metadata source plugin, but I'd like a plugin to pick up information from a custom column in the database. The identifier I rely on should be unique in the database, so in the "identify" method I can easily select the book record to get information from... if I can access the calibre database. (Any fast and easy way to get a book id from an identifier other than a search, too?)
