EDIT: XMonad can be made to play well with Unity: http://markhansen.co.nz/xmonad-ubuntu-oneiric/ (thanks hvr)
I'm looking for a tiling window manager to use with Unity. I would like the manager to place all the windows for me, as XMonad does, though I get the impression XMonad doesn't play well with Unity. Unity does have some tiling features (you can use keyboard shortcuts to eg send a window to the left half of the screen), but this is still lacking compared to what I want, as I want the manager to choose where to place windows on my behalf. Any ideas?
Thanks!

By choosing Place Windows in Windows Management you are able to individually define a fixed location for windows:
