This will change in the very near future. As more and more of our communications and entertainment is transmitted over the Internet thanks to email , instant messaging, video conferencing, and the emergence of Voice over Internet Protocol (VoIP) , Internet Protocol Television (IPTV) , and other protocols, a new wave of software driven innovations will eliminate the boundaries between the various modes of communications we use throughout the day.

Soon , you'll have a single identity that  spans all of the ways people can reach you , and you'll be able to move a conversation seamlessly between  voice ,  text ,  and  video  and  from one device to another as your location and information sharing needs change. You'll also have more control over how you can be reached and by whom: when you are busy, the software on the device at hand will know whether you can be interrupted, based on what you are doing and who is trying to reach you.
