I came to know about this video about future of pervasive Communication Application that makes your Location relevant and irrelevant and adapts to your moving between devices and locations, while reading a blog entry at Martin's Mobile Technology Page.
Here is the Video Link.
..this interesting video which shows the vision of the Daidalus project for pervasive communication in the future. There is lots of talk in the industry lately on voice call continuity, i.e. switching a voice call between circuit and packet switched networks. The vision of the Daidalus project goes one step beyond and shows how a call could be switched between different networks and devices and how additional information such as video streams and textual information are automatically included in the call when the current device allows and the situation requires. The roots of this concept are also known as "rich call".
