I'm ready to queue this now. Certainly any remaining snags can be fixed in-tree. It kind of keeps in tradition with proper software projects "plan to throw one away" which is what we have traditionally done several times: the first Bluetooh framework was tossed, JFFS was tossed for JFFS2, Video4Linux was tossed for V4L2. So let's do this. Anyone against? I will put it on an immutable branch and then merge that in for devel. Yours, Linus Walleij
