nsrCZ writes "The Skype core protocol has been reverse-engineered by a Chinese company. The interesting thing is, that although the protocol is closed, it is not patented and thus it is not against the law to crack it. If it's true, then it could affect the whole eBay/Skype business in many ways, including that they might not get their piece of the emerging Chinese cake." From the article: "By cracking the Skype protocol, the company claims it can also block Skype voice traffic, Paglee said. 'They could literally turn the lights off on Skype in China very, very quickly,' said Paglee, who is also a lawyer and engineer, speaking from California on Friday. The company could transfer the technology to the Chinese government, which has continually sought ways to tighten its filtering and control over the Internet. So far, the company doesn't have any plans to market its blocking capabilities, Paglee said."
