One thing which does not seem to be mentioned on the Astronomy Department website is that you can install IDL on your laptop and then get a copy of the department license. [http://www.exelisvis.com/MyAccount/Downloads/tabid/411/mv/vw2/id/6640/Default.aspx Download IDL] (you will have to create an account with exelis), and then follow [http://ittvisual.securehttp.internapcdn.net/secure_ittvisual/envi_5.1/web_install_all.htm?token=452697865220 these instructions]. There is also some information about licenses on the download instructions page. Copy the file /apps3/rsi/idl_8.3/license/license.dat from lupus in to whichever directory the ITT website tells you to use. Once you have done this, you'll need to set up your IDL environment with a .idlenv file, as described on the department guide http://astro.berkeley.edu/resources/computing/idlusers/idlsetup.html | One thing which does not seem to be mentioned on the Astronomy Department website is that you can install IDL on your laptop and then get a copy of the department license.
