*** I agree, it's not anything to write home about. However, for some applications (non X-related) it has potential. I know of one individual who wants to use LTSP to boot/configure diskless firewalls at various client locations. Not a bad idea - All that is needed is to boot the kernel and load a few ipchains/iptable rules and you're all set. Make sure the NFS export is mounted as read-only and it should be fairly tamper resistant.
