To what degree can one expect to extrapolate this behavior up/down/across the taxonomy of species? (I assume the more predatory, the more likely this would evolve.) Once you have a theory of mind, you can move from seemingly-intelligent but simply emergent "flock/herd" behavior to actual co-operation with peers or "disruption" of the out group, which would be interesting to look at. I think anyone who has had personal (and I mean personal!) dealings with crows can tell you they seem to have a theory of mind, and moreover, they hold grudges :)
