It would be AWESOME if there was a way to power buildcraft machines with EU because IMO buildcraft's energy system is far inferior to IC's system. Also, it would be nice to pipe liquids (lava) into machines (geothermal generators).
Edit: For the 2nd part of the suggestion: The Liquid API just became usable in 2.2.2 from my understanding. It's most likely already being looked into by the Dev team.
