    That will be easy.  The blockmap makes it easy.  HAMMER will be able to
    move physical big-blocks around on a whim.
That's one of the biggest reasons why I'd like to use it (next to 
keeping history).
It's so nice in ZFS to just don't care how large your partitions are 
initially, as you can increase them so easily.
