For me, the pipe system I want would be far more like the current Buildcraft than those of thermal dynamics or ender io. The recipes the recipes for both those mods pipes don't come close to hinting at the complicated item routing they allow. So, I would far prefer, for my own gameplay a somewhat simpler pipe system that requires a bit more thought. So basically BC pipes. The trick is, how to implement simple pipes that do not loose items or cause crashes, especially in the face of chunk loading. Buildcrafts existing behavior is such that pipes carrying items from a loaded chunk into an unloaded chunk will force the chunk to load. This bypasses server chunk loading restrictions and causes server reformable issues when entire bases get stuck in memory.
