Ditto! If I have guitars in cases I just don't end up playing them... plus the guitars make GREAT decorations (my wife even likes them).
I have a 7-guitar stand that folds into a case and it's nice for taking to gigs. I usually take 3 guitars for myself and our bassist will use one of the slots as well for his backup. Seven would be pretty cramped for a gig where you may end up wanting to take something out in a hurry, but it'd be a good "space-saver" for keeping the guitars out at home if you don't want to go the wall hanger route.
