From high atop the summit of Mount Fuji last summer, despite miserable weather and poor visibility, 32-year-old tech enthusiast Joseph Tame sent video coverage of a spectacular solar eclipse live to the Internet from an impromptu mobile-broadcasting studio. With little more than a laptop and a Web connection, Tame's high-altitude adventure was watched by about 370 viewers down below. Taming the Internet: Joseph Tame has used live-streaming video service Ustream to record his participation in the Tokyo Marathon and his climbs up Mount Fuji. The service is quickly catching on in Japan, which now boasts the second-largest Ustream user base in the world.
