I'm not very comfortable with multiplying multiple references to the "outside" in the doc, especially when the actual content is quite small and not very prone to change for now.

I'm thinking about a user inside a restricted DMZ (the kind of guy needing a relay :) ) that will see the link, and think "shit I can't download this now, I have to do it later from the open net" and get frustrated, wether in this case he could just do things offline by copypasting a short text.
