I wonder if there will be a comeback of self-hosted software in the near future just for the security and surveillance reasons, especially in business environment. There was the whole Cloud craze not so long ago, where many companies were pushing all their data outside local infrastructure, but I wonder if this is a good move in the long-term. SaaS has many advantages over "classic" solutions, but security and reliability was always a weak point and it may be a major factor against it in the future.
