mobile ad-hoc ephemeral groups : you are at a concert/conference, and someone launches a group , others with the app are notified based on the various criteria (geolocation, interest etc.) . you can subscribe and unsub as soon as an event or session is over. This protects privacy etc. as only an avatar is shared with others, you can message and talk with them, but disconnect once done. Can be used for announcements, notifications, 2-way comms etc.
