Which is what we call "bend over" security.

Alternatives:

1.  ssh -X -c des root@localhost  [1]
2.  su - ;  xauth merge ~regularuser/.Xauthority ;  export DISPLAY=:0.0
3.  "Sux".  http://fgouget.free.fr/sux/sux-readme.shtml

[1] "-c des" overrides default ssh cipher to single-DES for minimal overhead.
