My idea is to make a new pipe type, this particles act as a kind of powered pipe that only transports other things when powered.It would take particles from all three pipe-types and give it to "free space" if spark is applied. This element would have the same destruction properties as normal pipe this means with this element you could make destroyable gates that are smaller than pipe+e-wall. (sorry if you cant´t understand somethning english is not my 1st language)
actually, i like this idea. the only problem with this idea is it will have to be made by a modder before the moderators will think about implementing it. it is a very good idea though.
