Skype Protocol Has Been Reverse Engineered

From Slashdot: Skype Protocol Has Been Reverse Engineered

"One researcher has decided he wants to make Skype open source by reverse engineering the protocol the service uses. In fact, he claims to have already achieved that feat on a new skype-open-source blog. The source code has been posted for versions 1.x/3.x/4.x of Skype as well as details of the rc4 layer arithmetic encoding the service uses. While his intention may be to recreate Skype as an open source platform, it is doubtful he will get very far without facing an army of Microsoft lawyers. Skype is not an open platform, and Microsoft will want to keep it that way."
