Well, to answer the question: What are you doing now or what's happening? you could have users wearing glasses that collects video and sound from the environment and sends it into the network for recording and broadcast. The glasses may also have an inbuilt screen and headphones that can receive from the network. Getting lifestreaming right.

The glasses could also detect a user's emotions by their eye state and voice (or pulse.) It may autodetect location and detect sounds to attach environmental metadata -- so great metadata. Think The Terminator combined with Brainstorm.
