In response to detecting the data object identification request, a data object identification response is generated that identifies a data object in a second data store in the second execution environment. The second communications agent exchanges a second message with the first communications agent. The second message includes the data object identification response, wherein the second message does not include the data object.

Abstract: Methods and systems are described for coordinating playing of media streams. In one aspect, an access by a media player to a presentation device to play a media stream is detected. Additionally, presentation focus information is accessed for determining whether the media player has presentation focus for playing the media stream. Further, it is determine, based on the presentation focus information, that the media player has presentation focus for playing the media stream. Still further, in response to determining the media player has presentation focus, it is indicated that the media player is allowed to play the media stream via the presentation device.

Abstract: Descriptions are provided for processing a reference in a communication to a remote data object. In an aspect, information is received, by a second communications agent, that identifies a data object in a second data store in a second execution environment that includes the second communications agent. A descriptor is created for accessing the data object. The descriptor is sent in a first message, by the second communications agent, that is received by a first communications agent in a first execution environment, via a communications protocol. The data object is not included in the first message. A second message that identifies the data object is sent from the first communications agent to the second communications agent, via the communications protocol.
