JPEG arithmetic coding

The first specification of the JPEG image format was published more than 20 years ago and it obviously was a great success. Even after so many years, most digital cameras still produce .jpg images and a good portion of all images on the web are .jpg images. Now imagine if all .jpgs were about 10 percent smaller with exactly the same quality. Wouldn't that be nice?
