Later this year, an outfit call UrtheCast will contract the Russians to launch & fit 3 steerable HD cameras on the exterior of the ISS.
This will be a commercial venture, charging access time, so you could book your slot to film from orbit your carefully-timed outdoor wedding, son's footy game, natural disaster, etc. (Cloud insurance, anyone?!)
Resolution will be sub-meter range.
I'm still intrigued by the suggested pronunciation as "EarthCast" - it was clearly intended to be "U R the cast".
