Bandwidth-sensitive content sharing system

A method for bandwidth-sensitive content sharing can begin with the establishment of a content sharing session between two or more end-user devices by a bandwidth-sensitive content sharing system. At least one of the two or more end-user devices can be a mobile device having a network constraint and/or a data usage constraint. A bandwidth limitation can be determined for the mobile device from network connection data and user data. The bandwidth limitation can indicate a restriction to content sections of a content item the mobile device is to receive during the content sharing session. The content item shared with the mobile device can be filtered based upon a priority value for each content section of the content item. A content section can be an identifiable and discrete encapsulation of data within the content item. The filtered content item can satisfy the bandwidth limitation of the mobile device.
