Integrated, Neighborhood Schools; possible?

I just realized that one of my favorite authors, Jane Jacobs, in her book, "The Death and Birth of Great American Cities", stated that the one of the biggest obstacles to affordable, integrated, housing and integrated cities is the combination of zoning laws and neighborhood covenants. I would add to this Socialized Parking supported by Parking Requirements.
