I will point out that, according to some experts I've heard expound on the subject, interferometry doesn't work well in visible wavelengths of light, and that with current technology you almost need a physical connection between the two oberving points to time your observations such that interferometry is possible in the first place. Sort of put a huge damper on the concept of placing several large telescopes all over the globe to achieve a virtual aperature of thousands of km...
