IDEA: Gagdet(s) to combine mobile phone and computer

Hi,
  our most frequently used devices such as the mobile phone, computers, music player and car are strangely selfish devices. Even though there are protocols and properties they can achieve some synergy there is no pattern of this showing on the horizon. Even though phone and car or computer and car allow some sort of relationship where the car works as hands free kit there is no workings the other way round. For example trip notes and statistics for speed and mileage do not make it back to the phone or computer.

  At the work desk it could be quite useful if the computer would transmit a preview of everything currently in the clipboard to the mobile phone. That way one would not clutter the screen with extra information but it may come in useful to know what was last in the clipboard. The phone would also interact with the land line phone to use the preferred device for all calls.

  Another useful example would be if the music player could forward the audio to the mobile phone so that one can combine the budget music player and the standard phone. It appears that some manufacturer (such as Nokia) does indeed provide such a function when connecting computer and phone.  

  Really desirable would be a combination of computers. Sitting here at my desk and writing on one computer I have another computer connected via VPN for an intranet. I cannot multiplex my favorite keyboard to one or the other as appropriate. What would be simpler than to extend the bluetooth connection of one computer to proxy the keyboard output on demand.  Also, the computer is playing music from a streaming site. But without actually plugging in my stereo via the headphone output I cannot stream my output to the nearest audio visual system.  As one of the systems is an Apple and the other one a Microsoft based system I will push my luck in asking for the screens to be overlapping. Although each system allows multi monitor configuration.

  What is a required is a suitable capability broadcast functionality of all mobile and fixed devices that can collaborate in a grid of computer. Thereby a user can elect to have profiles in place to optimally use the best output and input devices for any kind of task ongoing.
