Elliot as usual phenomenal work accomplished. I was rereading some of the post and comments and I was thinking 
Computer control of the layout.: Smartest idea yet. Its to bad someone on the forum hasn't offered to write a program that would tie in everything from operating switches ,accessories, tying in the video feeds, but control the trains at the same time keeping proper spacing on the main and into the built up areas. This would also allow for local control of engines used for yard and switching at the same time. Not only would it be a leap in technology this would be a huge contribution to the hobby that would potently have applications in G,S,HO and N scales.
NMRA Certificates: Yep, would love to be the fly on the wall when they see the completed layout.
1. Because of the size of the layout and its in O scale.
2. The amount of buckets and mops you will need to clean up the liquid emancipating from their mouths. 
3. because you will most likely take all ten. They will have to create a new category. 
Just hope they don't find the skeletons in the closet. Then its over. 
Selling after your gone, like that will happen after all your work. Maybe when hell freezes over. I can see the ad, Layout for sale. Haunted House included. 
I agree we all have learned and gotten good ideas. Maybe a an OGR special, Layout from hell, What not to do, The trail and tribulations of a layout gone mad.
Cant wait for next month update!!!!!!
