PTS has nameplates in a very unfinished state -- but not so unfinished that it'd be ridiculous to imagine them coming to live in 1.9.

This seems like a good time to point out that there's some stuff it'd be really handy to be able to do to UI.Native.* windows, like :SetVisible(false) selectively, or attach our frames to them in a way that doesn't necessarily reveal the native window's absolute location.
