Until we install IMAX theaters in our homes, anything in excess of that isn't useful to a slngle end user. Users of satellite networks will be sorely disappointed with the latency of those systems, e.g., remote surgery with a 0.5 sec response lag. Joe David Farber wrote:

Looks like the Japanese satellite can handle two of those in the downlink direction at once. Jerry,it looks like we still have a ways to go.

Who am I to believe? ; ) Jerry Super-speed Internet satellite blasts off in Japan (CNN) -- Japan launched a rocket Saturday carrying a satellite that will test new technology that promises to deliver "super high-speed Internet" service to homes and businesses around the world. A rocket carrying a super-fast Internet satellite lifts off from its launch pad on the Japanese island of Tanagashima. The rocket carrying the WINDS satellite -- a joint project of the Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries -- lifted off its pad at 5:55 p.m. (0855 GMT). If the technology proves successful, subscribers with small dishes will connect to the Internet at speeds many times faster than what is now available over residential cable or DSL services. The Associated Press said the satellite would offer speeds of up to 1.2 gigabytes per second. The service initially would focus on the Asia-Pacific region close to Japan, a JAXA news release said. "Among other uses, this will make possible great advances in telemedicine, which will bring high-quality medical treatment to remote areas, and in distance education, connecting students and teachers separated by great distances," JAXA said. The rocket was launched from Japan's Yoshinobu Launch Complex at the Tanegashima Space Center. ________________________________ Delicious ideas to please the pickiest eaters.
