An unusual ventilation idea?

I have followed quite a few threads regarding ventilation. But I haven't found any discussion about using a simple vent exchange from room to room that basically starts the first room with a simple intake "port" fed in from the ventilated attic to the first room. The air would be further carried by a slow fan pulling it out of that room across an isolated duct of some sort in to the next room from ceiling level. Then another exchange would be made from the second room to the third using another fan and duct. The thrid room would be the last so an exhaust "port" would then feed back up to the vented attic and would be located a distance away from the intake port. Now the "ports" would not be attached to anything. Since the rooms would be airtight and isolated from one another, it seems like air pressure would make it easy to create a simple circulation cycle using the process mentioned above. You notice how you walk into the front door of your house and the back door shuts? Pressure. The air certainly moves the curtains! I would like to think this simple design would actually work. Hopefully someone will respond to this. I believe I am thinking of some osrt of positive ventilation scheme. Maybe the fan would need to be located in the attic to force the external air thru a port or duct into a room. And simply having a duct shoot from room to room until finally having an exhaust port would allow positive pressure to constantly push air through and out. No noise.
generally speaking you don't pull air room to room, you exchange the air in reach room with a single (or conceptually multiple) fresh air source. this avoids each subsequent room in the path getting more and more CO2, heat, etc built up.
