Using BC, RP2 and an automatic crafting table and those wonderful power converters you can set up an automatic lava cell refiller in the nether. Obviously, find a lava source. There might be a couple there. Geothermal generator to converter running a BC pump, attached directly to the pump. This will feed it lava directly without needing those messy pipes.<snip>
except one doesn't really need IC2 power to do that. a BC pump will happily run on 4 redstone engines at a decent speed once they warm up.
