I'm not an active participant in this thread, but I'm a anxious reader and hoping all gets decided here and now. Probaly It will be best to create a topic just to solve the little things between phobos and tango people that concern the general user.

I just have one comment are you sure that once something is released to public domain "...relinquishes any right to claim  authorship as well.", because here in Portugal everything that is done by a person is automatically protected as belonging to him. Registering the work and other things like patents (patents probably have other stuff but not relevant to my point) just help to garanty proof that it was made by that person. But unless it's specified otherwise no one can touch anything someone did. 

But what really relate to what you said is that, the only thing the author cannot do is denie autorship. If he made it, it's his, he can sell, give away everything (like the right to be used in any way, by anyone) except the right to be the author. It's called a undeniable "moral" right. And it just seems such a universal right that I repeat my question are you sure that authorship can be just given up?

This is to Walter now... it seems Tango coders would be willing to share Tango if they were to be quoted as authors of that piece of code, independently of the license used (sorry if I misunderstood). So I ask Walter if that is the only thing asked, does it still cause any troubles?

Sorry for the english.
