If I am not mistaken it's not the first time Skype send a DMCA to this project. But given where the autor lives, the DMCA does not apply so it doesn't go anywhere.

AFAIK the DMCA takedown applies to Github, who are in the US, regardless of where the author of the project lives.

Better link: https://github.com/github/dmca/blob/db9b442f0ac68512d0ca83fe...

even better link: https://github.com/github/dmca/blob/db9b442f0ac68512d0ca83fe... (rendered into human readable)

That is the exact link I posted?

Please note: this is not an attempt to clean-room reverse engineer Skype, or even to reverse engineer and create an open-source replacement. As shown with things like WINE, Microsoft does not (and probably cannot) take them down. No, that's not what "Skype Open Source" project is. This is a confusingly misnamed attempt to attach code to patched copies of copyrighted official Skype clients. Microsoft is not overreachi…

How exactly is one supposed to make a clean-room reverse engineering in the absence of any documentation and sophisticated obfuscation on Skype's part ?

It's hard, but people have made progress with that approach:

This project was recently discussed on HN at http://news.ycombinator.com/item?id=3899829

You linked to a discussion of a tool that lets you lookup the IP addresses of Skype users (which seems like it might have been developed with this tool), but I think you meant to link to https://news.ycombinator.com/item?id=3753155

Usually, that would mean reverse engineering to create specifications and then getting the product implemented by some one else using the specification which would then be termed as clean.
