Boost.Thread Clean Room Contest. Seriously, you seem to grossly overestimate software copyright protection (especially for thin layers like Boost.Thread taken in isolation). http://digital-law-online.info/lpdi1.0/treatise24.html <quote> Elements are filtered out of consideration on the basis of broad criteria, including: - The element's expression was dictated by reasons of efficiency, such as when it is the best way of performing a particular function. - The element's expression was dictated by external factors, such as using an existing file format or interoperating with another program. - The element's expression is a conventional way of writing something in the particular programming language or machine running the program. - The element, at the particular level of abstraction, is an unprotectable process and not protectable expression. - The element is taken from the public domain or is an unprotectable fact. Any protection for elements dictated by efficiency or external factors or processes must come from patents or trade secrets, if at all, and not from copyright. </quote> Hth. regards, alexander.
