Just got finished reading this analysis of Iran's government-run firewall. Based on his measurements of inbound/outbound traffic types, the author came to a conclusion:

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.

Good to know some people are hiding out from the madness with their level 80 shamans. Are World of Warcraft or Xbox Live already being employed as the next great means of covert communication, with Iranians telling their stories through crowded chat-logs full of gold-farming requests? Or are these measurements moot, merely proving that Iran's gamers have consistently hidden in their homes, plugged into the addictive ignorance of self-entertainment both before and after the election?
