It should not remind users of the underlying technology and make them forget that they are handling their own server. Instead it should be similar to the home screen of iOS devices with a simple navigation concept and very reduced complexity.

Therefore the interface should follow a clean, utilitarian approach with a focus on the task at hand. The interface should be accessible from any mobile or desktop browser.
