   I mostly agree with you but there is a couple of issues.   
      
   Even if you are as dark and cold as an asteroid, can you keep that up for days   
   as you cruise through space?   
      
   A very directed exhaust might not hit a sensor, but there are still enough   
   atoms in space that a sensitive enough sensor will detect them lighting up   
   under the massive plasma beam.   
   I was thinking to use a water jet at 10000 bar for a cold drive gas, but it   
   has some weight issues…    
      
   To go anywhere you will need to turn your drive on, and then people will know   
   your trajectory, and they will be able to calculate it very precisely, so even   
   if they can’t see you, they will still know where you are.    
      
   You would have to separate your craft from a booster section during boost, so   
   you would have a different trajectory than the booster part, but the mission   
   would then have to include a legal objective for the booster.
