Love the mary tyler moore show drop screen that raised and lowered, but don't think most 60's ranch houses have the ceiling height for it. . . she had high ceilings in dining to accomodate . . . what if you try the rolling door hardware and use a mod door style turned sideways or one of the cool 60's era screens they have at crestviewdoor.com look at the sandman - it is very closed http://www.crestviewdoors.com/capabilities/redi-screens/retro-wall-panels-mister-sandman-24x24.html so when it is open it still is art You could hinge a bunch together to be like a window designed to open all the way . . . search kitchen pass thru here on houzz too - lots of beautiful updates there . . . shelves below built into the design so it isn't just a bar . .

Photos and floor plan would be helpful.

This look and feel may help. http://rusticahardware.com/bi-parting-barn-door-hardware-system/
