So a friend and I are working on a new sorting system for a project we've been working on, we ended up building 80 digital chests, and the pipe systems in this modpack aren't exactly new to us, but we've found that pneumatic tubes don't interact with digital chests at all. Leaving us with Buildcraft pipes, which would be annoying, but not exactly a problem, except for the fact that these are all in a wall, with no spaces, so our only solution is to have a massive amount of sorting machines and cobblestone/stone pipes alternating to keep them from intersecting and piping items where we don't want them, does anyone have a solution to this?
