Streaming is most sensitive to how much data you can push through the pipe in a given amount of time, not to how long it takes for a question/answer pair to travel between the server and the client. Latency (how long it takes for messages to travel back and forth), which is where X11 over the network has major issue, doesn't matter in the specific case of watching a video. Essentially, once you press 'play', there's just a torrent of data flowing down from the server to the client with very little need for two-way banter between the machines.
