Highly interactive collaborative streaming applications express the need for causality. Solutions exist but we argue that more work needs to be done especially from a perceptual point of view. The key question is: given the current state of the Internet and the perceptual tolerance of causal desynchronization, does causality make any difference? This paper proposes a practical answer to this question by comparing different solutions. We support this comparison by producing video results for a live streaming scenario on an experimental platform. Further, this paper proposes a novel approach for handling causality in multimedia and shows that it can perform better than Δ-causality, usually considered the best solution.
