Serious question: what alternative would you recommend for access to NAS volumes from unix-like OSes (Linux, *BSD, MacOS) over LAN? Other than doing discrete file transfers over a channel like SSH, I'm at a loss for alternatives here to NFS and SMB. Given the two, if Windows is not involved on the LAN, I don't see why SMB makes any more sense than NFS. What other options am I missing?
