Somewhat relevant, the Open Mustard Seed project;

  The Open Mustard Seed (OMS) project is an open-source framework
   for developing and deploying web apps in a secure, 
  user-centric personal cloud. The framework provides a 
  stack of core technologies that work together to provide 
  a high level of security and ease of use when sharing and 
  collecting personal and environmental data, controlling 
  web-enabled devices, and engaging with others to 
  aggregate information and view the results of applied 
  computation via protected services.
