Sharing tape drives between NAS hosts is done by NetBackup tape drive multipathing - it's different to the traditional SSO.
From NetBackup 6.x you can configure more than one path for a tape drive - so you actually have one physical tape drive, and access it via multiple NAS hosts, that's possible with NetBackup.
A quote from "VERITAS NetBackup 6.0 Release Notes" page 11 for you.

Multi-path Shared Storage Option (SSO) for NDMP
This release of NetBackup offers a new dimension in drive configuration flexibility. Previous releases of NetBackup considered a drive to be shared only if the same drive was configured on more than one media server. This feature enables NetBackup to recognize multiple paths on a single media server to a single drive, making it possible for the same drive to be configured multiple times on one NetBackup media server. For the customer this means one media server can share all drives on all NAS/NDMP hosts and they need only have enough drives to sufficiently backup all filers.
