The latest gen Gogo internet Ku band satellites are suitable for streaming. Streaming isn't latency sensitive - in other words, if your video is 1 or 2 seconds behind no problem. You need bandwidth (ie mbps) for streaming, but latency (ms per packet of information to go from you to the satellite to the ground then back) doesn't really matter.

Real time synchronous connections (and in fact Outlook is a horribly talkative app, FYI) are where you notice that kind of thing impacting performance. VOIP is another example that doesn't do well on high latency connections (at all) unless tuned carefully and even then it's noticeable.
