+Person's status wall display
+
+The app is designed to run unattented without human interaction
+on an always-on android device, periodically fetching the
+last location information, and the last event from a configured
+calendar, interpreting th latter as the phone call record.
+The tracked person carries on him or her an Android handset with
+the app 'CallTrack' installed to sync the call log records to
+a calendar, and Latitude enabled. The 'wall display' app runs on
+another Android device, like an ebook reader with e-ink display
+(and network connectivity). On initial setup, this app is granted
+access to the tracked person's location and calendar via OAuth2.
