Abstract: In some embodiments, a processor-readable medium includes code representing instructions to cause a processor to perform a process. The code stored by the processor-readable medium includes code to cause the processor to allocate a portion of a display screen of a first device to be uniquely associated with a second device and to send to the second device a directive representing a symbol appearing on the display screen when a user-selected indicator is received. The user-selected indicator is associated with the portion of the display screen of the first device. The first device is mutually exclusive from the second device.

Abstract: In one embodiment, a processor-readable medium stores code representing instructions that when executed cause a processor to receive a first signal at a mobile device, the first signal including a mobile instant message having inline image data, the inline image data defining an image. The processor-readable medium stores code further representing instructions that when executed cause the processor to receive an edit command associated with the image and send a second signal, the second signal including a mobile instant message having a directive based at least in part on the edit command.
