Dear Art, I am the sysadmin, which is bad news since I am much better as a crystallographer... and I was working on a different issue on the same machine the past week.
Our institut has a good firewall so I believe we'll be fine, the installation of Arp/warp was smooth after the modification of grub as you proposed. Thank you very much!
