neotix your idea is a step more and in my opion good (also played with Buildcraft and RedPower) - but i think not possible in factorio. also includes a automated pull in and out from a chest (terminal). if i really hard change/swap the gfx - i maybe can make a 10 tiles long inserter and sell this as pipe-segment. for crossings it would be a cross-segment (green inserter entity ^^) - in any case a very interesting idea and sould be tested

with some code it can be look and play better and comes more realistic
