Searching for Free Software's Shared Space

Sharing lies at the heart of free software, so I was naturally intrigued to read about the concept of "shared space" traffic management in WorldChanging:

The premise of shared space is that people pay more attention when they're not distracted by "highway clutter," in the words of its founder, traffic engineer Hans Monderman. Shared space relies on environmental context--in this case, a landscape unlittered by signs--to influence human behavior. "Our behavior in a theatre or a church differs from a pub or in a football stadium as we understand the signs and signals through years of cultural immersion," Monderman told an interviewer in 2006. "Likewise if we see children playing in the street, we are more likely to slow down than if we saw a sign saying 'Danger, Children!'"

Put less diplomatically, shared space makes people confused. People who are confused slow down, calming traffic and reducing accidents. That's exactly how it has worked in Bohmte, where city officials plan to gradually expand the program to include other public spaces where pedestrians and cyclists share roads with drivers--roads, in other words, other than highways. The changes have had the added benefit of improving the experience of walking or cycling down the road, as a maze of unattractive signs and lane markers have given way to a single stretch of red-brick-colored pavement and as drivers have moderated their speeds.

Fascinating. But I can't quite work out what it all means for free software: anyone have any suggestions?
