I agree completely, I'm working on a paper right now for a conference
(waiting on Wireshark to finish with my complex filter at the moment) that
shows what's happening with gaming traffic. What's really interesting is
how gaming is changing and within the next few years I do expect a lot of
games to move into the remote rendering world. I've tested several and the
numbers are pretty substantial. You need to have <=30 ms of latency to
sustain 1080p gaming and obviously jitter and packet loss are also
problematic. The traffic is also pretty impressive with spikes of over 50
mbps down and sustained averages over 21 mbps. Upstream traffic isn't any
more of an issue than "normal" online gaming. Nvidia, Google, and a host
of start ups are all in the mix with a lot of people predicting Sony and
Microsoft will be (or are already) working on pure cloud consoles.
