If memory serves Linux is just getting around to proper private/dynamic namespacing as of some recent version, or so I was told by a friend contributing to the kernel. Linux has been slow, but steady at adopting features out of Plan9 as listed in the paste you provided. Most of the features are incomplete once ported, however. All features and the depth of things like /proc aren't fully transferable to *nix due to architecture, kernel design, or other oddities. Plan9's kernel, while small, deviates from most commonly found kernels in that things such as networking are built-in and expected from the moment booting takes place.
