I didn't do a research before writing the above notes... Also, regarding the patch that adds the ability to the server to chroot users, do you refer to the http://chrootssh.sourceforge.net project or there is another patch?

Therefore being able to use these things on a local LAN for example without the overhead of encryption is incredibly useful. @George. I think much of the HPN-SSH patches were bug/design fixes and they've mostly been rolled into the official tree in different forms (though it took years for them to do it). I also found the simple patch to provide chroot access to a user very useful. @Mihai. openssh provides many features in addition to encryption (like [X] forwarding etc.), and hence many more things are built on top of the interface it provides.

SSH is definitely not useless without encryption. All, that is mandatory, is a 100% trusted environment. @Atmatzidis:Although I am not an expert to benchmark all those protocols, I don't think they are faster than an encryption-free SSH connection for the reason that SSH is a much simpler protocol implementation than <code>SAMBA</code>, <code>NFS</code>, <code>HTTP</code> and possibly <code>FTP</code>. Even, if it is not faster than the aforementioned protocols, it cannot be that slow. The truth is I haven't used SSH in such a way yet, but I plan to do so in the near future. Then, I will be able to write a few things accompanied by actual tests.

The whole point of using openssh for networking or any other stuff is because it provides encryption. If you just want unencrypted networking there are other programs out there that don't provide encryption. the cypher none patch makes openssh pretty much useless.
