Well, why can't he set something up like

remote host controlling the library
You don't need
anything special to do this (such as the SSO). Matter of fact, the Veritas Class
I just got done taking has this exact setup (Quantum M1500 library with two
drives, each drive controlled by a UNIX server with one of the servers being the
robot control host) and we didn't have anything special beyond the base
NetBackup installation. Media Server #3 has no physical access to the DRIVES that Media Server #2 sees. Sure, NetBackup can tell MS # 2 to mount a tape, but MS # 3 has no path to the actual tape devices. This goes beyond the "robot control host" functionality.

There's not much hope of a different media server being
able to write to these tape drives. If you want a system to share tape
drives, you need some sort of physical connection between the media server and
the tape drives.
If you have a SAN but don't have your tape drives SAN
connected, you could consider a fibre to SCSI bridge and share those tape
drives. If you don't have a SAN at all, the costs probably aren't
justified.

We
want to add now four drive in our our existing Library & connect it to
third media server.
Please let me know is that possible.
Will this 3rd media server have direct access to
the tape drives? In other words, are the tape drives SAN-connected or
are they SCSI connected to the existing media servers?
If the tape
drives are SAN-connected, then what you want to do is fairly straight-forward.
You need to purchase the Shared Storage Option licenses and then you
would configure the tape drives to use the right robot control hosts.
You can dedicate tape drives to media servers - one way to do this is to
use SAN zoning.
