The bidirectional connection is separate from a multimedia connection that transfers a multimedia stream from the multimedia stream distribution system to the user. Providing a bidirectional connection separate from the multimedia connection is advantageous, among other reasons, because the operational data can be collected effectively at the multimedia stream distribution system independent of any limitations in the multimedia connection. To organize users and reduce processing load, the multimedia stream distribution system assigns users to user groups based on shared characteristics. Groups may be used to propagate information to the users as well as analyze information collected from the users in an efficient manner. ## Claims ### Claim 1 A method for remotely communicating with a user over a network comprising: by a connection handling component of a computing device for transmitting multimedia items to a plurality of users, creating a user profile for each of a plurality of users, the user profile describing characteristics of a corresponding user; by an application component of the computing device, assigning a first subset of the plurality of users to a first user group and a second subset of the plurality of users to a second user group based on user profiles of the plurality of users, the first subset of the plurality of users having user profiles sharing at least one common characteristic, the second subset of the plurality of users having user profiles sharing at least another common characteristic; by the connection handling component, establishing a bi-directional connection between the computing device and a user of the first user group or the second user group, the bi-directional connection configured to transmit operational data representing data associated with at least one of content, quality, and process of reproducing the multimedia items at the user; by the connection handling component, establishing a one-way connection with the user, the one-way connection separate from the bi-directional connection and configured to transmit the multimedia items from the computing device to the user; and by the connection handling component, sending the multimedia items to the user through the one-way connection responsive to establishing the one-way connection between the computing device and the user. ### Claim 2 (depends on 1) The method of claim 1, wherein the user profile comprises characteristics collected from the user. ### Claim 3 (depends on 1) The method of claim 1, further comprising: responsive to propagating the communication to the first user group or the second user group, receiving feedback data from members of the first user group or the second user group via the bi-directional connection; processing the feedback data into a set of aggregate statistics; and updating the aggregate statistics responsive to receiving additional feedback data from additional members of the first user group or the second user group. ### Claim 4 (depends on 3) The method of claim 3, further comprising sending the updated aggregate statistics to the members of the first user group or the second user group. ### Claim 5 (depends on 1) The method of claim 1, wherein creating the user profile comprises copying the user profile from a first component of the computing device to a second component of the computing device to reduce a computation load at the first component. ### Claim 6 (depends on 1) The method of claim 1, wherein transmissions of operational data over the first connection are initiated at a source of the operational data. ### Claim 7 A computing system for transmitting multimedia items to a plurality of users over a network comprising: a connection handling component configured to: establish a bi-directional connection between a user and the computing system, the bi-directional connection configured to transmit operational data representing data associated with at least one of content, quality, and process of reproducing a multimedia item at the user; and create a user profile for each of the plurality of users, the user profile describing characteristics of a corresponding user; a streaming component configured to establish a one-way connection with the user, the one-way connection separate from the bi-directional connection and configured to transmit the multimedia items from the computing system to the user; and an application component configured to: assign a first subset of the plurality of users to a first user group and a second subset of the plurality of users to a second user group based on user profiles of the plurality of users, the first subset of the plurality of users having user profiles sharing at least one common characteristic, the second subset of the plurality of users having user profiles sharing at least another common characteristic; and communicate with the plurality of users by propagating a communication to the first user group or the second user group. ### Claim 8 (depends on 7) The system of claim 7, wherein the connection handling component is configured to establish the bi-directional connection responsive to receiving a request for a multimedia item. ### Claim 9 (depends on 7) The system of claim 7, wherein the operational data comprises at least one of information describing a network connection quality associated with the user, client device information, and user interaction data. ### Claim 10 (depends on 7) The computing system of claim 7, wherein the user profile comprises characteristics collected from the user. ### Claim 11 (depends on 7) The computing system of claim 7, wherein the application component is further configured to: responsive to propagating the communication to the first user group or the second user group, receive feedback data from members of the first user group or the second user group via the bi-directional connection;
