In this paper, we propose a new approach to live location sharing among a group of friends that does not rely on a central server as a hub for exchanging locations messages, but is done in a peer-to-peer manner by pushing selective location updates via XMPP messages. That is, only those contacts specically authorized by users will be noticed of location changes via push messages, but no third-party service is involved in processing these locations. We describe an initial implementation called Friends Radar, and discuss the associated trade-offs between privacy and resource consumption.
