UrtheCast is putting high definition cameras on the International Space Station and streaming footage of Earth directly to the web. There's some amazing images here - http://www.urthecast.com/firstlight
Looks like they plan to play in the $1.5 billion Earth observation industry selling to gov'ts (who knew). They also have a consumer facing web platform + an API for developers. Don't think these guys will be flying under the radar for long :)
