The guys at http://www.rstack.org have done quite a bit of work on
Skype (and more particularly Skype security), the Chinese DIDN'T
"crack" the Skype protocol they were simply the first people to
release an alternative client.
Rstack.org's were the first to "crack" the protocol, the details can
be found in Philippe Biondi's and Fabrice Desclaux's blackhat
briefings eu 2006 presentation "Silver Needle in Skype";

Further work was done later into Skype-based botnets, details are
available in Cedric Blancher's "Fire in the Skype" presentation;

Actully not to belittle team RStack (hi guys, and girls) and their work
but the first analysis I saw of the Skype protocol was the 2004
paper from Salman A. Baset and Henning Shulzrinne at the
CS dept. of Columbia University. This paper started a lot of
other research.
Just to give credit where credit is due.
