Yea ultimately the clients will need to do the verification themselves, I
only meant to have somewhat more useful mirrors (corrupted data,  bugs
in scripts, etc) it would make sense for mirrors to verify that the data they
are getting is the data they are expecting so they don't serve bad data. While
a verifying client won't be affected by that bad data, it does lower the overall
availability for that file.
