UL has, or had, a whole house in Fremont (maybe Milpitas) associated with their Fremont lab location for testing Wi-Fi/Bluetooth/etc interoperability in a "real-world" setting. They're not the only test lab to do something like that, either. It would not surprise me at all if Apple had a similar facility for themselves, especially for internal demos, user testing, and sanity checks.
