Iranian Traffic Filtering

There's a good couple of articles at Arbor on how Iran is filtering the traffic in and out of the country. The first is an overview of the traffic shaping, the second goes deeper into what seems to be occurring. I've included a picture from the site showing the traffic being blocked.
The most interesting take away that I had was that they are completely ignoring WoW, XBox and some other game-oriented traffic. An amusing (and accurate) conclusion is reached by Craig Labovitz:
"Perhaps games provide a possible source of covert channels (e.g. “Bring your elves to the castle on the island of Azeroth and we’ll plan the next Ahmadinejad protest rally?”)"
