hmm assuming the current nether mod does reduce by the right 8, a track though nether from mine an syls to spawn will take 24 stacks of iron i think and a boat load of chinese slave labour to build a safe track though the nether.
or it's going to take a bit over 1,000,000 (2000 double chests) of cobble to make a 3 wide flowing (ie powered you you get in at one end and it will take you all the way without further input) via duct to out place from spawn.
hmmm..
