Awesome, I was thinking of something like this.
Technically, if the items are fluids, that means the throughput is almost unlimited, so is the transfer speed, you can input items on one side and output them on the other side extremely fast. Plus if you have several input stations for the same item time all feeding into the same pipe and several output stations on the other side, you can send a LOT of items through really quickly.
The only downside is that belts can mix items, pipes can't.
EDIT : Just downloaded the mod, I have a few questions :
Recipe multiplier warns to keep #items * fluid/items under 150, fluid/item warns to keep it under 100. Which one is it ?
Also is "recipe multiplier" the same as #items ?
