What sort of job are your users running? If it's a non-interactive
parallel job, you could put a 'jobStartup.m' on the path which displays
the required information - this is available in the tasks' command
window output property.

See <http://www.mathworks.co.uk/help/toolbox/distcomp/jobstartup.html>
for more on jobStartup.m.
