Just a warning for those attempting this using 1.9: Snow destroys torches and saplings. I don't mean it pops them from the ground, I mean that it replaces them entirely! This was a minor setback for me because I didn't notice my torches and saplings disappearing while focusing on my cobble generator.
My eventual goal is to build a snow golem village. It's a lot of fun! Sometimes it's great to play a map where you actually have to manage resources.
