Can you hit two different targets with and deal sneak attack damage to both?

We came a cross this problem when one our players a Rogue/Soulbolt used Lethal Acrobatics by moving in between two foes threatened space. Tactical map wise the foes were standing one square apart from each other and our Rogue/Soulbolt tumbled through the square between them and at the end of the tumble about the rest of his movement action distance he used the ability Double Shot to hit the two target that should be Flat-footed till he ends his turn.

  1. Can you use Lethal Acrobatics vs multiple targets?
  2. If so are you allowed Sneak attack damage to both?
