Kenton, thanks for all of the work you and your contributors do on sandstorm.io; I have referred this project to many people wanting to get their feet wet "running a server" as a way to do something without instantly cutting yourself. Have you considered writing a how-to article on replicating ownCloud-like functionality within Sandstorm using apps? It might be a good first step, and I believe that it has the possibility to help people move onto (what I personally believe is) a superior platform.
