Six Optical Telescopes Combined Into One

00Paddy writes: "Starstuff.org reports on how astronomers successfully combined the light from six independent telescopes to form a single, high-resolution image of a distant multiple-star system using interferometry techniques. The combined telescopes gives a effective mirror diameter of 430 meters, much bigger than any single mirror could be made. This technology will lead to images of sunspots of distant stars and maybe images Jupiter-sized planets orbiting distant stars."

Whay can't this be done on a planet scale?

If you can make a 430-meter diameter telescope in this way, why can't a 10,000-meter diameter telescope be made by doing the same thing with hundreds or thousands of telescopes all across a hemisphere?
