No cipher option

[nbecker at fred.net]

I noticed that "no cipher" is not an option in recent open-ssh.

I wish there was an option.  I'd like to use ssh as a replacement for
rsh in

rsh machine1 "tar -f - " | rsh machine2 "tar -f - "

But for massive file copies, I really don't want to go through
encryption.  Still, I would like the strong authentication offered by
ssh.  So I think "cipher none" would be a good choice here.
