But if you try to turn Plan9 into a lean UNIX, you lose everything that Plan9 advocates. In particular, I don't see how you can possibly integrate namespaces into UNIX in any meaningful way. Without those, it's no longer Plan9, and therefore a pointless endeavour.

The release of the 10th Edition UNIX source is much more enlightening. Here you can see a fully functional UNIX with what, 29?, system calls? And you can see the genesis of many of the Plan9 concepts (/proc, dial(), mk, mux, etc).
