Some fine news from China. A FOSS communications system based on the Skype protocol may soon become a reality. The protocol has been reverse-engineered
by a group in China. Communications by chinese using Skype are being censored
by the Chinese government. Because Skype and its protocol are proprietary, the Chinese government has been able to censor chosen information by striking a deal with the copyright holder. If a FOSS project attempted to do this, the users would always be free to escape.
