Technology Watch: At Telephony Online, Ed Gubbins has three pieces on the coming explosion of internet traffic due to video, video calls, virtual worlds, P2P file sharing, business IT traffic, and remote backup services.  In the first, he discusses how the carriers are scrambling to catch up; in the second, he discusses George Gilder’s claim that demand is increasing so quickly that bandwidth prices may start rising soon; and in the third, he says the problem is even worse than the carriers think, and that they need to get ahead of it rather than just catching up.
