Project, it was possible to connect to X on any LTSP client from any
host on the network, making client windows and keystrokes visible to
that host.

NOTE: most ldm installs are likely to be in a chroot environment
exported over NFS, and will not be upgraded merely by upgrading the
server itself. For example, on the i386 architecture, to upgrade ldm
will likely require :

    chroot /opt/ltsp/i386 apt-get update chroot /opt/ltsp/i386 apt-get
    dist-upgrade"
