"It allows you to easily host your own website, email, 'cloud' and more, all within arm's reach. It does this by interfacing with existing software and allowing the user to easily update and change settings with a graphical interface. No more need to depend on external cloud services, which can be insecure 'walled gardens' that require you to give up control over your data. arkOS will have several different components that come together to make a seamless self-hosting experience possible on your Raspberry Pi. Each of these components will work with each other out-of-the-box, allowing you to host your websites, email, social networking accounts, cloud services, and many other things from your arkOS node."
You should definately have a look into this!
