Cipher 'none'

[Rachit Siamwalla]

I agree with people who want the option to allow cipher "none". I use
ssh primarily for its secure authentication capabilities, not
necessarily for its encryption of data. I use it to do secure RPC's
within a network. I don't particularly care if some evil guy breaks into
my network and sees what RPC's i'm doing, i just want to make sure the
evil guy cannot make those RPC's to my machines themselves. Also, some
of these RPCs are data intensive, moving gigabytes of data back and
forth.

Also, having the capability to allow "FallbackToRSH" is probably much
worse than allowing "Cipher none" in the first place. If you guys think
that ssh should not have the "Cipher none" on the grounds of being
afraid of the user shooting themselves in the foot, then we definitely
don't want the other option either.
