I have been using the facility of X apps to fowraed to a remote server.

This is the script I use to start and redirect an X application
(kaffeine) to a machine that has logged in with ssh

#!/bin/sh
# start in the right place
cd /var/videos
# this fixes some errors that I don't understand
export $(dbus-launch)
#detect IP address of remote client
IP=`echo $SSH_CONNECTION | awk '{print $1}'`
#redirect pulse audio to it
PULSE_SERVER=$IP:'4713'
# set default X display to remote client
DISPLAY=$IP:0.0
# DBUS_SESSION_BUS_ADDRESS=""
export PULSE_SERVER
export DISPLAY
#kaffeine > /dev/null 2>&1
kaffeine


On the client machines you need something like

xhost +
ssh -t myserver pathtomyscript

assuming you have passwordless ssh set up.

Ex of gigabit ethernet, this isn't fast enough to play movies, but its
good enough for most other purposes
