All Roads Lead to IPThe Internet continues to expand, swallowing up all media along the way. Data communication already is based on TCP/IP (Transmission Control Protocol/Internet Protocol). In five years voice will be transmitted over IP, and within ten years video also will be routed by IP, beating out "digital broadcasting", which has been bucking the Internet wave. But this does not mean that IP is optimal for any medium. On the contrary, IP is not good for any use other than data communication.
