OpenMosix would be a different approach. My understanding is that it migrates processes automagically as needed to maintain even load between multiple servers.
Though, it seems that SSH should work fine if they are all on the same local network.
I just ran this command on my ltsp server and it is very fast: ssh 192.168.0.7 /opt/firefox1.0/firefox (different machine)
Be careful, this will encrypt your X traffic which will load your LTSP server and application perhaps for no good reason.
Perhaps it would be better to set your DISPLAY variable to your terminal rather than the tunnel.
From ssh man page
X11 and TCP forwarding
If the ForwardX11 variable is set to "yes" (or see the description of the -X and -x
options described later) and the user is using X11 (the DISPLAY environment variable
is set), the connection to the X11 display is automatically forwarded to the remote
side in such a way that any X11 programs started from the shell (or command) will go
through the encrypted channel, and the connection to the real X server will be made
from the local machine. The user should not manually set DISPLAY. Forwarding of
X11 connections can be configured on the command line or in configuration files.
ssh -x 192.168.0.7 DISPLAY=$DISPLAY /opt/firefox1.0/firefox
This tells ssh not to forward X and sets the display varable to the terminal .
Could it be your network or server performance?
