technically there is no difference here.

but from an administrative point of view there is.
the zone administration (zones "root") is often
"delegated" to some other person(s) then the one
administering the GZ. the zones "root" position
may be fullfilled by an internal or external client
of the entity that administers and own the GZ and
the corresponding HW itself.

one must just be more aware of the fact that there's no
restricted access to such a tape device then in normal
situations because its so easy to forgett that
you've given away the tape device so some NGZ
in the past.
