==Better suggestion needed for my RedHatism== 

 This one put in by me because I couldn't think of a better one. X Window System - the diagram of a server and clients. I even asked on the talk page and got no better ideas for a remote client than up2date. 

 The key factor I'm looking for here is an application that is routinely run as a remote X session. Can you think of any that aren't quite so specific? 

 (And we'll never mind that the graphical nature of up2date is incredibly stupid. I disliked Linux before administering it for a living, now I despise it.) 

 If you can, please suggest it on Talk:X Window System and I'll redo the image, or I can send you the SVG (I did it in Inkscape) and you can go wild with it -) -
