Logistics Pipes is an extensive overhaul of the Buildcraft pipe system. It allows for better distribution of items via pipes, more organised stockkeeping and easier automated crafting.
This Logistics Pipes is universal. That means you can use it in singleplayer and multiplayer.
You need Minecraft Forge and BuildCraft to run it, but we also added features to collaborate with a few other mods.
The mod is contributed under the MMPL.
