THAT easy?
Nice. So ideally I should just be able to copy the folder of the LS install I already have onto a pendrive, and... Oh SWEET. That I have to try.

Edit:
Now that I give it more thought, I don't know why I expected it to be more complex. I guess the only semi-permanent change made is setting LS to boot instead of explorer.exe, but since I can just run it manually through the task manager, I don't need to do that...

Edit Again:
Having copied my LS directory over to the pendrive, reset my default shell to explorer, and rebooted, I could run it off the pendrive no problem on my home computer, and it went straight back to explorer when I rebooted.
Now I just need to hope there's no odd sh*t going on with the Uni's network regarding explorer. Should work though.
