You can get a live view of Earth from the International Space Station approximately 30% to 40% of the time, at best.  I know of two ways to get to this view from the Space Station.  One way is to go to directly to the link at UStream (warning: this link occasionally causes my browser to lock up) - Live ISS Stream from NASA.  The other way is to get to the link via NASA TV where once you're on NASA TV you go to "Space Station Views" and then click on "Flash (UStream)".  There are five sites that I know of for tracking the Space Station and they are: NASA's site, Real Time Satellite Tracking, Heavens Above [occasionally shows other satellites instead of the Space Station], ISS Tracker and SPACE.cweb.NL.
