Yeah works well with it and only weighs in at 5MB.. so all up, to have a wobbly desktop it costs about 20M compressed,, not bad.So we now have Xfce as the top candidate for compiz.
I guess the whole lot could be packaged with a special xinitrc that doesn't overwrite the current one... build it into wm switcher and it should be simple to switch between compiz and the other wms (switching the xinitrc in the process). I did note that X just refuses to start with the others.
Cheers
