For this task, I used to use net/unison{-devel}.
It can synchronize file hierarchies with a bi-directional  
synchronization, so that you always get the latest version, and will  
ask in case of conflicts.
It depends on ocaml (and eventually lablgtk if you want a gui), and  
works fine on netbsd, among others, and is pretty efficient.
