While the Iranian government has cracked down on communications by restricting Internet traffic during the ongoing post-election unrest, an analysis performed by Craig Labovitz of Security to the Core suggests that authorities aren't paying attention to the flow of online game data:
While the rapidly evolving Iranian firewall has blocked web, video and most forms of interactive communication, not all Internet applications appear impacted. Interestingly, game protocols like xbox and World of Warcraft show little evidence of government manipulation.
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?”)
Meanwhile, Xbox 360 gamer Mike Murikami, blogging for The Examiner, notes:
With the Xbox 360 offering video chat among the features of being an Xbox Gold subscriber, this could easily be an upcoming popular way for loved ones and news outlets to deliver messages to and from the country.
