Pipe!?! Pipe!?! PIPE!?! Seriously!?! Buildcraft is already a deprecated Mod. Pretty much the only unreplaced content it adds is Oil. And Buildcraft has as far as I know Gates for that purpose, no need to attach Computercraft to it.
LOL, BC gates can only tell if there is power flowing, not the level of power.
I use BC pipes a lot. The quarry is far superior to the IC2 miner and I use the BC pump to pull lava from the nether to power geo gens.
I have several autocrafting rigs setup to make stuff for me. like Overclocker upgrades, solar arrays, gears, construction foam...etc. I just dump the needed resources in the right chests and they do the rest.
