Zone systems are designed to open and close dampers based on demand. But there will be a "dump" zone, where the excess air will go when it is not needed. A lot of zone systems also are on two-stage equipment where the system can check the demand and maybe only bring on the first stage of the compressor and fans, then ramp up as needed if the demand increases.

I get that with zoned systems that were designed that way...but I see a ton of stuff for retrofitting a system to be zoned. In those cases you are basically just doing the same thing as shutting off a register... or am I off base here? So basically you are saying shutting off registers or half-ass retrofitting won;t do you a lick of good?

Cool. I think I'll tell them to go that route. At that point should they just cap off the duct running to that room or should they leave it as is and use the ductless unit to supplement it?
