A have an Xtreamer multimedia player.
It can access and mount NFS shares.
In my Ubuntu computer I have to edit the /etc/exports file and insert:
The corresponding NFS configuration line in Xtreamer is:
/NFS Shortcut/[xtreamer_mountpoint] ->[ubuntu_computer_ip]:/[Ubuntu_folder] -o rsize=32768,wsize=32768,tcp
Do not forget to port forward the 2049 port (NFS) in the router.
