OMG, that is so cool! We are trying to figure out our ventilation, and will be putting in 3 stations. I think this could work in a slightly modified way for us. Thank you so much for posting!
Where did you get the fan? I need to start sourcing this stuff since we need an electrician to come in and put in a sub panel and wiring. Which means I need to read all the ventilation posts, for the 5th time!
