The equipment, perhaps. The procedure, no. If a D registered, or F registered, or G registered or VH registered airline flies a quad from Europe to the U.S. or from Australia to the U.S. then they abide by the country of registration's rule - that means that they divert as and when - and where - they wish, not into the nearest alternate as may be mandated by the FAA for N registered aircraft. The captain may elect to do so, but he is not forced to. As I said before, not everyone's regs are governed by the FAA. There's a small grouping on the other side of the Atlantic as well (what are they called this week? Still EASA?) who have their own rules.
Phileas - a good point well made. Tri-jets fit here as well. I wouldn't go so far as to call the MD-11 "finest" though. DC-10 perhaps of its generation. But the MD-11 not.
