Well, I was hoping for many more than just two. I don't really see any other way than many competing projects, one eventually killing all others. But it shouldn't be that painful. As you've said, it's mostly about toolkits, and it's easy to simply run X server atop of the new system (Mac OS X does that, Linux does that in some ways, Windows can do that, so anybody can). I guess that the terrible mess of Linux audio can be avoided (after all, you don't have X11 applications locking whole graphic system for just themselves, as is often the case in audio).
