Previously I was pumped lava out of the nether using ender chests and liquid transposers and a chunk loader, but I'm trying to avoid putting that sort of stress on the server. Currently I have a 10.3 mB iron tank that is being fed by three magma crucibles which are each fed by an igneous extractor. The iron tank is supporting six magmatic engines which are powering the crucibles. Six magmatic engines produce 24 MJ/t. Three magma crucibles require 60 MJ/t. I think you can see that this isn't going to work, even if the magmatic engines are only drawing from the tank when empty. (Sidebar: I want to monitor the magmatic engines fuel capacity and only activate the redstone torch that's powering the liquiduct when all the fuel is gone. Since I'm using liquiducts, I can't use gates. What's the solution here?) One of the other players on my server had suggested switching to geothermal generators, fed by the iron tank, to power electrical engines that have been upgraded with iron electron tubes. Geothermal generator produces 20 EU/t and the modified electrical engine will produce 10 MJ/t. Six geothermals, six modified electrical engines, 60 MJ/t. I should note here that the ultimate goal is to use the (hopefully) unlimited lava supply to power a steam boiler. Unfortunately I'm just not sure if that's going to work out, I think I may be headed in the direction of a hugeass iron tank that powers and feeds itself and nothing else.
