After you successfully rsync, be sure to download the MD5SUM file again. The checksums may have changed. Why would that happen? Because there's another difference between the official Fedora Core, and the official Speakup Modified Fedora Core. Bill keeps the Speakup Modified updated with newly released RPMs, whereas the release version of Fedora Core remains unchanged forever. So, when you install the Speakup Modified, you're always getting the latest releases as of the time you download the file.
