    That's an interesting comparison, since the Amiga windowing system does
    guarantee a backing-store for all windows. If Intuition can do it, why
    not X?

How does Intuition do it?  Does it pop up a message: "Please insert floppy
number 137, I need to save/retrieve some backing-store bits" ?  They must be
trading off something somewhere.  For example, do they guarantee backing-store
regardless of how big you later make the window?  Does that mean they
preallocate max-sized memory chunks for every window created?  Is there a
small limit to the number of windows that can be created?  Or does the
"guarantee" mean the system will crash unexpectedly at some point?

    Speaking of clients and servers, the NeWS people don't seem to use the same
    polarity of terminology. Am I misunderstanding or is there a conflict here?

The X terminology is from the point of view of the network connections.
The thing that listens for and accepts connections from others is the server,
the thing that attempt to establish a connection is the client.  This is
quite consistent with the terminology in Sun's "NeWS Technical Overview", so
I don't know which "NeWS people" you are talking about (maybe ones who've
lost their backing store :-).
