Whats the big hurdle with administration? It sounds easy to add user, is there anything else? Or is it the administration of the entire solution that is timeconsuming? I looked at dropbox teams, but that felt expensive at the time and didnt offer any good groupwide sharing capabilities. But price-wise it will probably be cheaper than the proposed ms-setup.
