   I know that I've asked this before a long time ago, on an NG far, far away,   
   but what about using a robotic camera to do this - something like   
   AERCam/Sprint??   
      
   IIRC, the main concern seemed to be if a thruster failed on and caused a   
   collision, but surely materials technology is good enough now to allow the   
   thing to be padded heavily in sponge rubber and you wouldn't want to fly it   
   too fast anyway..
