Is there a hash in the header that yum could use to realize which packages are the same? I could see a situation where repositories you thought were the same diverge for reasons beyond a user's control (repo A has been purchased by a new corporation and the new manager decides to no longer carry video games, so repo A stops carrying Frozen Bubble. Meanwhile, repo B continues to carry games as they have for the past 2 years, including Frozen Bubble). Therefore, I think I would rather have this equality test at the package level, not the repository level. Hashes would work to implement this--if you get meta data on a package and see two packages from two different repositories with the same hash, you know they're the same package.
