This made me laugh (in a good way). I agree, it actually does make total sense - but that doesn't mean I won't get confused :). My only prior exposure to "GUIs over the network" were web applications, where the roles are essentially reversed. That is, the part responsible for accepting user input and rendering the UI is the client (the browser), and the part that performs the application logic is the server. I naively assumed that X would work the same way, but it wasn't too hard to unlearn that misconception.
