I have that FIM DVD ISO, just never posted about it in /pone/ before:

Concerning thing about IPFS:
> $ ipfs cat QmYbSUMaromwPd9JRMgSqLHV57iz8Wj6VXYth4qa1NSQio
> mmm
> $ xxd .ipfs/blocks/KL/CIQJQXV6WCXW2E6WAU4XYUDEDYGIHQOWVME3OIC47H6VTELZTOP5KLA.data
> 00000000: 0a0a 0802 1204 6d6d 6d0a 1804 ......mmm...

That shows that bits were flipped in the .data files: simulated corruption. ipfs pin commands (incl. the verify one) didn't catch that, and neither did a gateway:

It's this (not flp->QmYb...SQio):
> $ echo mmm | ipfs add
> added QmYbSUMaromwPd9JRMgSqLHV57iz8Wj6VXYth4qa1NSQio

So for now, it seems like BitTorrent has better data verification.
