offtopic but, my fiance is cool with my two arcades and wasn't against me getting 2 more when some were offered to me
that's why she's my fiance and not my girlfriend

anyway, you could do what i did before and just make a control panel
i made a 4 player one that fit perfect on my coffee table in front of my couch
that way you can put it up and only bring it out when you want to play
you could also hack some wireless xbox 360 controllers in there so you don't have any wires between you and your setup
that's what i would do if i had your problem
btw, i have a ms.pacman and although you would "fit" with the street fighter setup, i wouldn't recommend it
it works perfect for one player games (or multiplayer games where you take turns)
but i would be too cramped with two people, but then again, i'm also a pretty big guy
