ACSLS, though, would fall into the category of "using another software
package as an interface".  I suspected ACSLS could do that but didn't
want volunteer that since I don't have firsthand knowledge of it.

I suppose it revolves around how one defines "partitioning the library":
        Hard partitions or soft (by tape label ranges).

We have a Sun/STK SL8500 with ACSLS as the front end and have several
(unrelated) Netback Master servers (and media servers) all using the 
library concurrently.

We have not "hard partitioned" it, but rather have a tape range and
specific
tape drives assigned to each Netbackup system. We even have several 
non-Netbackup systems also using the library.
