I think that this would be useful enough in itself, e.g. when syncing
database storage files. The chance that blocks move around (without
changing) isn't that large. I've been considering something like that a
while... Useful when syncing a 40GB database when there's mainly only
insertions. I never had the time to persue it, though...
