I'm setting up a fileserver, and I want lots of clients to easily access it. Up to now I've always used SSHFS to share between different PCs, but since I'm setting up a single fileserver, I'm looking for other common alternatives. Up to now I've seen:

AFS: It seems it has no security, traffic is unencrypted, so it would require an SSH tunnel. If I'm to use SSH, I'd just use SSHFS.

NFS: Same as above. Also, setting up the server is not so straighforward, it doesn't seem to be KISS enough - at least not for my liking.

SMB: Same as AFS. It also seems not to be too well documented, and technically, seems a bit poor. It also seems the protocol isn't formally standardized.

SSHFS has security, but as a downside, requieres every user to have an account on the server - there's no way to make a certain directory PUBLIC either. I don't think it has locking, and isn't very fault-tolerant.

Are there any alternatives I've missing?
