"At 8th level, whenever a scout moves more than 10 feet in a round and makes an attack action, the attack deals sneak attack damage as if the target was flat-footed. If the scout makes more than one attack this turn, this ability only applies to the first attack. Foes with uncanny dodge are immune to this ability."
This would work great for a ranged attack using rogue! Especially if you are using shot on the run eh?  Move, attack with a bow getting sneak attack dmg, then still have another bow shot with normal damage.
