thanks very much, greg. as it happens, and i didn't realize this until i experimented a little more after sending note, the right-click-on-desktop "Configure desktop" menu allows for separate configuration also, down to running a separate program -- xplanet, kworldclock, say -- on each desktop. which i tried for a minute or two, then decided to have my moon desktop on the lower monitor and plain black on the top monitor. subject to change.
i'm really liking this.
