All groups can see and hear a multicast event and experience the reaction of others to the event.
You may reserve a table in advance to sit with friends, or you may just decide to go to a virtual town hall to see who is there, or you might go to a virtual music club to listen to a band. In order to make virtual clubs widely available, it is important to enable communication services which are tailored to suit users' available bandwidth. For users with high bandwidth connections, the system provides high quality video communication services. A user can, for example, focus on an individual or group of friends, viewing them in high quality video, while keeping track of what's happening in the background utilizing reduced quality communications. If a nearby conversation sounds interesting, the user can easily move to join that group and focus on them.
