FT, I like that M-drive link. I think I'll borrow that. 
Doyle, IMTU the gradient of the G field depends on the size of the ship and follows inverse-square. A vessel with a single deck would have a non-uniform field as you suggest. However, I have adopted the idea of a 'positive' plate in the floor and a 'negative' plate in the ceiling. This provides a little over 1G at feet and head, and about 0.5 G at stomach. Takes a special breed. On a big liner, though, you can put a big G plate on the bottom deck, put 4 decks of fuel tanks above it, and have a pretty constant field in the higher decks.
