[CEATEC 09] DoCoMo (a Japanese wireless carrier) was presenting this connected intercom that turns mobile phones into an intercom. If someone rings your doorbell, your phone will ring and you can see and talk to that person via an audio+video connection from your mobile. After that, you can open the door and even turn the lights on and control a few more things in your home. Thanks to DoCoMo, I will finally know if the Fedex guy really stopped by or not.
