Unison will sync files over ssh just fine.  NFS is not needed if SSH
is used.

    unison ./foo/ ssh://example.com/foo/

This requires compatible versions of unison on both systems.  That's
perhaps somewhat more restrictive of a statement than might seem at
first glance.  Unison is often rolling versions with incompatible
protocols.  That's why there are so many possible ones to install.

    $ apt-cache search ^unison
    unison - file-synchronization tool for Unix and Windows
    unison-gtk - file-synchronization tool for Unix and Windows with GTK+ interface
    unison-2.52 - file-synchronization tool for Unix and Windows
    unison-2.52-gtk - file-synchronization tool for Unix and Windows with GTK+ interface
    unison-2.53 - file-synchronization tool for Unix and Windows
    unison-2.53-gtk - file-synchronization tool for Unix and Windows with GTK+ interface
    unison2.27.57 - file-synchronization tool for Unix and Windows
    unison2.32.52 - file-synchronization tool for Unix and Windows
    unison2.40.102 - file-synchronization tool for Unix and Windows

If working between two different system versions you will need to
install compatible versions on both.
