Tape library sharing between NetApp NAS and media server

I am working on a backup topology design. The customer has one NetApp SAN/NAS with FC tape out port, and one HP MSL tape library with two FC LTO5 drives. They will have a BE 2010 or BE 2012 media server with FC port, and several Hyper-V with FC ports. All FC ports connects to the SAN switch.

The question is that is it possible to use one tape library to backup NAS using NDMP, as well backup those Hyper-V LAN-free? If yes, what license do they need? I know if using NBU, they just  need a SSO. How about for BE? Any difference if use BE 2010 or BE 2012?

Thanks,

Henry
