While I can see the merit in doing this for AV reasons, it makes very very 
little sense for a the case when mt DVD download failed because the last 200 
bytes were ruined (I mean at storage level on the server) and all you want is 
to download those 200 bytes from a second mirror.

But as Henrik said, lots of "download accelerators" already work exactly like 
this and clearly it works fine enough for a certain amount of people.
