An alternative to this which I've been pondering, is munin.  The idea being
that the server (or another server) could run the munin monitoring/graphing
software and the ltsp chroot could be running munin-node (or perhaps


This would give us memory usage, cpu usage, network bandwidth and other
information from each thin client individually.  This would hopefully be a
big help in diagnosing problems on thin clients.  There would probably be
some tricks involved in automatically monitoring all thin clients (you
might need to set up static ips?).
