Not sure if anyone has mentioned or noticed, but BuildCraft is going huge as TF2 competitive players would call it. It seems Spacetoad coming back has pulled the whole project out of maintenance mode. The Builder is mostly working again and the next major release will see its comeback along with the accompanying Architect Table and Blueprints. Of interest to players that don't use popular mods like Thermal Expansion with its Autonomous Activator and Terrain Smasher is the fact that the Stripes Pipe is also back! It both sucks blocks out of the world and places them. I have seen them used in the past for some awesome farms.
They should just start over from scratch and make a new buildcraft already.
