My first thought was perhaps a wrapper script around Star Office that
inserts a randomly weighted pause of up to 10 seconds before starting
up SOffice? This would be annoying, however, in normal use, so something
a little more sophisticated that could log how many apps were attempting
to startup in the last 5 or 10 seconds, and implement some sort of
waiting queue before starting additional copies, might be better. Has
anyone ever benchmarked how long it takes to start 30 sequential copies
of SOffice, vs just banging go on 30 machines at the same time?

A generic app queue control might be a really good thing for making a
K12LTSP server work better with low amounts of RAM. Or does one already
