Now, it ain't tiling, but I once worked (not as the first guy, but took it over as a major project and the hell out of it) was one of the ports of Opebox-ish Windows managers (to be more accurate, really an Explorer replacement shell, not a Windows manager traditionally) to Windows XP to build very stripped down Windows kiosk machines with minimal UI and a lot of control, custom UI, and cool fun features.
God I miss this. It was way ahead of the time and I guess Microsoft got their UI act together, then lost it, and are trying to find it again.
As for tiling, the best you can do are these:

The latter is by a budding Chicken Lisp; I found him and love a lot of what he does; not sure he is ready for prime-time.
