Window tape used to come in the KOP (until 2001?). It is a black nylon ribbon about 1/8" thick that has rectangular cutouts in it that keep it tracking on pulleys. I believe it is available through Small Parts. (Don't remember because we have so much of it we haven't bought it in a while.)
We have a design that allows us to use the "track" on the tape to both extend and retract the arm with a motor driving it. We drive the arm up the tape more or less. Below are the best 2 picture I could find on our website. We have used this mechanism in 98, 99, 01, and 03. I'll see about getting some better pictures of it at tonight's meeting.
