the problem with exporting the tape device to a NGZ, which although
not "supported" can be achived as you mention,
is that there's no way to exclusive assign that particular tape device 
to a particular NGZ or to restrict access from the GZ or any other
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.
