Jeff Pulver describes his desire for federated presence that cut across consumer applications. When someone of Jeff’s leadership in P2P, SIP and Real-time Communication technologies highlights a need for presence aware applications, people should listen. To me, his request highlights a couple of key points:
1) Presence means something different to different people. Is it "on-line"…or "available"… or "interruptable"?
2) A federated clearing house of presence information that is served up across multiple applications
3) Intelligent "connectedness" that is more "context-aware" than "presence-aware"
