The question should be posed in this current rush of ambient life questions, should we be able to use ambient life as spies?  If you remember, in StarCraft you could infect other units for a temporary amount of time, I believe that this would be a useful ability in Halo Wars as well.  If we take it a step further we can use ambient life such as Space Owls to carry our spy equipment.  As they fly around the map they could de-fog the area they are currently in and give useful map information to the player. 

What do you think.  Would this be a plus to the game?  Also, should ambient life be accepted as spies, should enemy units also be able to be used as spies?
