If you combine the new Moto X with the Moto Hint you essentially have this listening only to you. That would enable you to say "OK [Moto], Launch Instagram" and it hear you regardless of people around you (specifying that due to a follow up comment you've already received). You can already say "OK Google [Now], [Open|Launch] Twitter" and it should work.
