Given you're using volumes for datasets where ZFS knows nothing about
the contained filesystem structure, about the only way to proceed is via
the windows site of things.  You'ld need to somehow trap where windows
issues a write and proceed from there.  Ideally you could do something
like snapshot NTFS, wait until windows has written something and then
compare the snapshot with the live filesystem.  Very cursory Googling
suggests that Microsoft calls this sort of thing a 'shadow copy'
