I share my media on an Ubuntu server via NFS - all I've done is set the shared media library as read-only for the devices it's shared with, and specify the (local, reserved) IP it should be sent to. The only authentication is the fact that it's LAN-only, and being sent to the right (local) IP Kerberos would be far too complex to be warranted here - all that's needed is nfs-kernel-server and /etc/exports on the server side. Granted, my network is reasonably locked-down (MAC address filtering, (reserved) IP addresses available matching the number of devices on the network), but security beyond that has never really crossed my mind.
