It works pretty well. Like I say, if you set the /books folder to the same data folder as calibre, when you download a book, it will autoimport into calibre. It will pop up a dialog for you to save the book locally, just cancel because calibre will have imported the temp file it creates on the filesystem. Then make sure you’ve set the Calibre Autoimport to delete source files.

Fix the IRC name in the openbooks config below
