I believe the hash feature is useful in that if you rename a file and
rescan, it picks up the new name and retains the metadata information
from the old name.
That comment you refer to looks like I put it there when I changed the
way the backend IP addresses are stored in the database. I don't know
what that has to do with the hash.
I do not know anything about how the hash is calculated and used so I
can't help there.
