In the Book's Vision all Real Objects are always connected to the Real Object Server, the Connection allows Remote Method Invocations any time on both sides. The Client can always retrieve important Server Information (i.e. Game Status) and the Server can observe the Client's behaviour and take measures as needed (i.e. Disqualification). The Vision represents the perfect ROApp Framework regardless of Data Traffic, GPS Fix Problems, GSM/GPRS Signal Strengths or Energy Management of the Device.
