Nicely done. We did the same kind of seperation of X & Apps but make the
scripting a little different:

-There is no need for expect or tcl, juist

ssh-keygen -t rsa -f ~/.ssh/id_rsa -C '' -N ''

will generate keys without the need for user intervention.
Likewise will 

ssh-keyscan -t rsa "appserver_ip,xserver_ip " > ~/.ssh/known_hosts

obsolete the need for user intervention while handshaking with the
server.

We put this as a little script in de /etc/X11/xinit/xinitrc.d/ dir so
the keys are generated on the fly while users login through GDM/KDM.
The old keys are throw away while logging out with the purge_user
script. (added for a little more security).

The appserver needs it's home dirs to be mounted on the X_server because
apps like mozilla and openoffice generate a lot of userdependant data,
also does it make for consistent file browsing to be on "1" server.

Kind regards,
