Mac Lion server for pushing images to labs

Is anyone in the educational field using a Lion server to push images out to Mac labs, and if so how is it working and what software are you using to accomplish this? (I am interested in pushing actual images out to the lab, not in having the lab computers boot from the server.) Is anyone using Deploy Studio? or Netinstall? or does anyone know the differences in how these programs work for this? After the push out, do you have to manually go around to each lab computer to do anything for it to work? I am trying to decide what route to take to accomplish this for about 60 lab computers.
