This is more like what I was looking for. I tried the command above. but 
ssh did not recognize the -Y option.
I tried it without the -Y (in KDE Konsole) : `ssh user at host 
/usr/bin/kwrite` and got 'kwrite: cannot connect to X server'.

I did not completely understand all your instructions. So I googled and 
foudn this HOWTO which I'll give a good read ( 
http://www.tldp.org/HOWTO/XDMCP-HOWTO/ ). But can this be done with KDM 
and KDE as that's what I normally use?
And does this require the headless machine to be at runlevel 3?
