What is the open pipe in the middle of the plumbing for your double sink with dw and disposal that sometimes backs up and spews all over under the sink and is it correct or required?
It could very well be an "Air admittance valve." Plumbing systems require a smooth flow of air and water to operate properly, these vents historically were routed through the roof and allow for the relief of positive and negative pressures in the vent system. "Air admittance valves" are installed under sinks and lavatories that are inconvienient to route a vent to the roof. These vents while handy do not respond well to back pressure, they are designed to seal during moments of positive pressure and "breathe" while in moments of negative pressure, this is to prevent sewer gas from entering the room. The purpose of the trap is to prevent sewer gas from entering the room, the purpose of the vent is to relieve positive and negative pressures in the drain and vent system to prevent trap seal loss. The slang name for an "air admittance valve" is studor vent. "Studor" is a manufacturer of AAV's Hope this helps

Sewage line cheater vent?
Im not familiar with the term cheater vent. Perhaps you are referring to an Automatic Air Vent or Air Admittance Valve? They are installed per the manufacturers reccomendations. Some municipalitys around the US recognize these, but do not allow them. They work on the basis that once installed if there is negative pressure in the waste arm from the act of water being flushed through the p-trap and down the waste line they allow air to be entered into the system to protect the trap seal.

If your stench pipe terminates inside the building how can the system be vented?
I haven't heard it called THAT before. Most of the time it's called a "vent" pipe. Anyway, they typically vent to the outside, straight up through the roof. Anything else is in violation of building and public health codes. You can ventilate the pipe with an air admittance valve . A device which lets air in but not the smell out . It would save having to go through the roof e.t.c.
