My girlfriend was talking about wishing there was a more "magical" house (and a place to put 300 books on bookshelves), and then she mentioned "Well, could we just use a spell to teleport us someplace like that in a mod? Oh, wait, what about a nifty floating doorway, that should be easier than a travel spell when there are no travel spells."
I'm not sure if the game is possible of creating a "bound door", but I just figured I would throw that out there as a thought.
Thanks
