MirrorBrain could become a "hash server": Whenever a suffix like ".md5" or
"sha256" is appended to an URL, MirrorBrain could return the corresponding hash.
Would be really cool.
Easy to implement, once issue 40 is done.
Serving the hashes by appending the corresponding file suffix, like .md5, could
shadow existing .md5 files; likewise for sha1 files. But I think it would still be
worthwhile and it wouldn't matter at all.
