Now that Samba 4 has been released we are gearing up to release a new version of Winexe which will be based on the latest Samba 4 sode. The Winexe source code in our "current" (a.k.a. "winexe-waf") Git repository is at least beta quality and you are cordially invited to grab it, build it according to the directions in the README file, try it out and send us feedback.
