Certainly the development was led here at first. @dpshelio was involved early on as well but i don't remember about the "founding" moment. I guess it also depends on what you define as "founding". I know that the Python was first discussed at SIPWorks. @dpshelio, @wafels do you remember more? If @dpshelio (or anyone else) thinks that this statement is not accurate I am happy to remove it (or add to it).
