This was initially an experiment on my ectremely n00bish skills. It's quite simply the command 'gksu nautilus' typed into a text file and made executable. So..remember to make it executable after you download it. Then put it in your scripts folder, and restart nautilus.
Done!
USE: right click on a white space in any folder and it will reopen that folder with the gksu argument, I think thats the right terminology for it
Works in my Ubuntu 11.10 if it doesn't work in yours...oops.
