Yes, precisely. I was doing this for a secure intranet, so it was no big deal from security's standpoint; but I wanted to get the sysadmins to push out the settings change to everyone, and they said "It can't be done" — meaning, "We can't be bothered." So I had to post a little explanation on how to modify one's own IE settings for this feature to work. Which means, It doesn't work. :-/
