Hello,

  I would like to propose Cozy a personal cloud based on Node.js. It's architectured like a PaaS. So it allows anyone to build its own application and to share it with other Cozy user via a simple Git URLs. The main apps are calendar, file, email and contact manager. We already have a nice community around the project.

By the way, thank you for awesome-nodejs that is ... awesome ;).
