AFAIK the host in ComputerCraft were the server. I remember how some people done quarries in the 1.4-1.7 versions of Minecraft (I don't exactly remember which) by simply putting a chunk loader object from other mod and programming the robot to mine it. The robot had a diamond pickaxe and could drop and get items, so when the inventory were full, it could drop all of the objects in a chest or other place.
