Here's my XRandR and multi-screen patch, its pretty much not what you've asked for here, but I'll throw it out as a starting point. I haven't had a chance to test it much, so don't yell at me if your screen explodes...
one tag for all screens. status bar is only shown on screen 0 (although this can very easily be set to another screen) layouts updated for multi-head: tile: windows are evenly divided among screens. monocle: one window per screen, all remaining windows on last screen.
