content native to the first one of the client-computing devices.

9. A system comprising:

one or more processors, and

a memory coupled to the processors comprising instructions executable by the processors, wherein the processors are operable when executing the instructions to:

send, to a plurality of client computing devices that are each associated with a particular user identifier, conversation-group information that identifies a conversation group, wherein the conversation-group information comprises:

a user identifier of a first user of the conversation group, wherein the user identifier of the first user is associated with a first one of the client computing devices; and

a server identifier of a streaming server for the conversation group;

receive, from the first one of the client computing devices, a first audio stream and a first video stream;

receive, from each of one or more of the client computing devices other than the first one of the client computing devices, a request to access the conversation group;

receive, from each of one or more of the client computing devices other than the first one of the client computing devices, a second audio stream and a second video stream associated with the particular user identifier associated with the client computing device;

receive, from one of the client computing devices other than the first one of the client computing devices, a request to view a set of conversation groups that the client computing device is permitted to access;

in response to the request to view the set of conversation groups that the client computing device is permitted to access, querying one or more tracking servers to determine the set of conversation groups that the client computing device is permitted to access;

determine video streams associated with the conversation groups in the set of conversation groups that the client computing device is permitted to access;

select a representative video stream for each of the conversation groups in the set of conversation groups that the client computing device is permitted to access, wherein each representative video stream comprises a video stream associated with a user identifier of a first user of the conversation group;

send, to each of one or more of the client computing devices other than the first one of the client computing devices, in response to the request from the client computing device, the first audio stream, the first video stream, one or more of the second audio streams, and one or more of the second videos streams, wherein before being sent the first and second audio streams are mixed into a final audio stream and the streaming server provides for concurrent display on the client computing device both the first and second video streams; and

send, to the client computing device, the representative video streams for concurrent display on the client computing device.

10. The system of claim 9 , wherein:

sending the first audio stream and the second audio stream from the streaming server comprises sending an ambient audio stream; and

mixing the first and second audio streams into a final stream comprises mixing the ambient audio stream into the final stream.

11. The system of claim 10 , wherein the streaming server selects the ambient audio stream from an ambient-audio-stream provider.

12. The system of claim 9 , wherein the processors are further operable when executing the instructions to select, based on user preferences associated with a user of the client computing device, a subset of conversation groups from the set of conversation groups that the client computing device is permitted to access.

13. The system of claim 9 , wherein mixing the first and second audio streams into a final audio stream comprises synchronizing the first and second audio streams with each other.
