Platforms that support group-awareness and group interaction enable mobile users to have a rich knowledge about the whereabouts and activities of people with whom they work or live or have a shared interest. Context-based group-awareness enables members of a loosely-formed group to maintain the right balance between autonomy, privacy, and awareness. Previous work in this regard focuses on under-standing the dynamics of groups and group members; on recognizing and sharing contexts; and on tackling scalability concerns. Little work has been done on the dynamic provision of service that are not foreseen when a group is formed.
