moritz:

Just a general note: At many institutions, even the USB keys are locked down so you can't use 'em. It can be a real chore to get permission to get code onto systems. I've had to fight that battle at previous places of employment. For production systems, it can be a tremendous pain. Luckily, I could install CPAN modules onto my personal computer, so for many tasks like the OPs, I'd develop a one-off on my own computer to automate a task.
