This is an academic environment.
Telling users to adjust the way they do things is an exercise in
futility. It's hard enough trying to get them not to put 100k of small
files in one directory and then complain about access speeds.
Finding things like a massive IDL program being written to simply call
wget 20 times is common (never mind that what was wanted could be done
with one wget command)...
