Yeah, for some reason I got it stuck in my head that this is where we'd need
that, but we won't need it until we get a little higher up.  For instance, when
you ssh somewhere the RSA stuff just encrypts your symmetric session key.  Your
actual session is encrypted using IDEA or Blowfish or something.  I'm
dumb...I've changed it and uploaded the changes.

fixed that too :)
