I find it difficult to believe that this is the right place to introduce
redundancy. Including a hash with each part so that you can detect broken
ones is useful. Sending out multiple copies seems like a waste of bandwidth.
And if you really want to do this, wouldn't it be easier to just post them
multiple times?
