CodeProject friends have launched a contest about Internet Of Things based on Azure wich is very nice. The prize is $10 K (subject to the typical restrictions), and the interesting thing is that it is open to any idea you have and use devices and Azure to collect, aggregate, and explote data.
From what I understand, can range from the typical temperature sensor in your home by sending this information to AZURE to scenarios more complex with several integrated devices between if and trying to conquer the world.
The only problem is that the scenario you are describing in your article must be published and ready before March 23, so you have all this weekend to finish a nice article on the subject.
