Achievement notification in a real-world achievement system

We propose a global system for acquisition, maintenance and communication of achievements in the real-world. The main focus of the proposal lies on a context-aware notification service for achievements. Users of the system can browse the achievement web application and will only get notifications of users within the same context. The definition of context is based on the network infrastructure of the client accessing the system. Our server utilizes information derived from IP-routing traces to build the notification groups.
