Just back from Marbella, went into the local B&O dealer in Puerto Banus. They have the complete cinema set up, 3metre projection screen 4 belab 5s and some software they claim is theirs (not B&Os) to make everything work. They have servers with a massive library (no need for discs etc), and off course the backlit beo4 and shutters to exclude light. I imagine they have soundproofing as the sound is absolutely awesome.
Tempted to buy and bring on the plane but didn't have enough cash... They said they are the biggest in Spain, I don't know if they were showing off, but 100metres away is the marina with some pretty big boats.
