\_ Can anyone point me to some documentation on allowing specific hosts to
\_ connect and display on remote X servers in a passwordless fashion.

YMMV:

server % xhost +a.client-ip.com

client % xclock -display a.server-ip.com  # to test ... can't corrupt
                                          # much with xclock

man xhost, xauth.

ipchains, and ssh may also have amusing information.
