In an embodiment, objects are downloaded to an access terminal (AT) based on which window(s) are prominently displayed on the AT. In another embodiment, objects are downloaded to the AT based on a set of user-specified object download priorities. In another embodiment, a portion of a streaming data session to the AT is de-prioritized in response to a transition of a display of the AT from a first set of windows associated with the streaming data session to a second set of windows associated with a different session. For example, the de-prioritization can result in the portion (e.g., a video-portion of a audio and video conference) being omitted or reduced. In another embodiment, in response to the AT entering a limited environment, objects being downloaded to the AT can be dynamically altered to conform with the AT's limited environment.
