[FreeNX-kNX] X forwarding to FreeNX server?

Hi,

I am interested in using FreeNX on the frontend node of a small Linux cluster.  I'm
intending to use Sun Grid Engine to manage the grid tasks, since one of the most
attractive features is to be able to launch tasks on the frontend node which are then
assigned transparently to the execution nodes.  One thing I would like to do is to
configure SGE to use rsh to launch tasks, and have them connect to the Xserver running
on the frontend node for GUIs.  I have configured this fine for the raw Xserver if one
is sat at the frontend node, since configuring X to accept TCP connections is
straight-forward enough.  However, if I connect to the frontend node using a FreeNX
connection from somewhere else, the forwarding fails.  How can I get my application,
running on an execution node, to connect to the FreeNX server (?) running on the
frontend node to display my GUI?

Any help *very* gratefully received, as I don't want to configure SGE to use ssh (messy
passwords or keys).

Thanks,

Chris
