Sounds like rsync can already do that (I am not sure right now, if rsync can
find updated areas within a large file, or if it just copies the while updated
file even if it is a large one)...

Furthermore the remote consumer of that gmirror couldnt be mounted RW, if it
uses UFS, because UFS doesnt allow multiple RW mounts at the same time...
