I'll leave it to the Japanese to develop standards for device cooperation. They go bananas for this sort of stuff.
Fujitsu's "Task Computing" promises automatic integration of all sorts of devices, automatic function discovery, and minimal input from humans.
Well, I'll believe it when I see it. That's all I have to say.

Fujitsu Labs and Fujitsu Laboratories of America have jointly developed "Task Computing Technology," which is a technology that allows for the cooperation of multiple devices (such as cellular terminals) and the operation of these devices through o­ne another.

"Task Computing Technology" consists of the connection of devices with supporting middleware and software, allowing them to cooperate with o­ne another's functions through a network. A feature of the technology is its ability to comprehend the features of a device connected to it, with no input from human beings - this is so that users can use various combinations of devices without having to worry about detailed connection settings.

For example, if o­ne were to carry a cellular phone into a presentation room, the phone would automatically recognize devices in the area it can use, it could also display documents o­n the screen from PCs in the area, or even playback music files stored in the phone o­n the room's speakers.

Fujitsu plans o­n first integrating the technology into the industry as well as considering standardization, and plans o­n implementing it in 2005.
