Yesterday, Netflix introduced a new UI for Android phones that brings it more in line with the tablet version. While most of the new features were detailed in a video, they apparently missed one major selling point: the app can now be used to control the Netflix app on a PS3 running on the same Wi-Fi network.

It seems that not everyone has this feature yet - we've seen a few comments here and there form users who can't seem to replicate what happens in this video, even under the same circumstances. However, the proof is in the pudding - the feature exists, so it's probably only a matter of time before it's more widely available.
