the problem with exporting the tape device to a NGZ, which although

is that there's no way to exclusive assign that particular tape device

NGZ to that same tape device. that might become a problem
if several different users try to use that tape from different
NGZs or a NGZ and the GZ, that access may produce a somewhat
questionable end result that care must be taken here when
setting up such configuration.

Where do you see a difference from many different users trying to access the
same tape from the Global Zone?

The difference is that in the global zone there is the possibility
for applications to coordinate with each other because they
have visibility into what each is doing, whereas in non-global
zones there is no visibility from one zone to another.
