Oh, it doesn't? I'm mildly disappointed. Those seemed so nice. :-)

There is a way to handle a hash tree where only the top level hash needs to be handed out centrally. Then any other node can send you data for a block plus at most logb n hashes where b is the block size and n is the total file size in order for you to verify the block it sent. And usually it's a lot less.
