[Dirvish] Is this a dumb idea? rsync without ssh

[Barton C Massey]

Doesn't this work?

  RSYNC_RSH="/bin/ssh -c arcfour"; export RSYNC_RSH

RC4 is practically free, and modern SSH doesn't always
support "null" for no obvious reason that I am aware of.

You may need to alter the flags in authorized_keys on the
client side to match this.
