I thought openssh removed the "none" cipher totally, so you can't even turn it
on with a compile time switch. And when you could use it with ssh1, it wasn't
really ideal, as passwords are then sent plaintext.
I looked into this to do tape backups to a remote tape drive. In order to
keep the tape drive streaming, it needs data at a certain minimum rate. ssh
with encryption wasn't fast enough, but rsh was. It was less trouble to
temporarily enable rsh than to get ssh working without encryption.
