Today I received a call through Skype from a friend at a company in China, except he told me he was not using Skype to call me. His company has successfully reverse engineered the Skype protocol and he wanted to call me in the United States to see how it worked between physically distant IP addresses. We talked for a little over nine minutes before the call dropped. Then I called him back using my Skype and we spoke for another three minutes.

The first time we talked there was a noticeable echo on my end. The second time the voice quality was good ol’ Skype crystal clear. At present they only support placing Skype peer-to-peer phone calls and they have not yet implemented presence. They have plans to add presence, instant messaging, and a host of other features. Their end goal is to create a client 100% compatible with Skype. They sent me a screen shot of their software (below) and my IP address was 100% correct.

The advent of the release of this software raises many interesting issues. According to their CEO, their software will not support Skype’s Super Node technology. Right now every computer with Skype installed on it can be used as a relay to carry data between two other computers when both of those computers are only allowed to make outgoing TCP calls. This means that very soon Skype users will have an alternative client which will not hijack their computer. This could eventually have a very negative effect on the Skype network if too many people choose not to act as Skype Super Nodes and the network starts to deteriorate.

Well... if it doesn't support supernodes, then I assume they are looking at a client server model?
