Merril Lynch
Merril Lynch has a big office in Houston. They would have a big problem if a hurricane were to hit the place. To guard against this they have another office in an inland city that is essentially a continuously updated electronic replica. At a moment's notice they can packup, come here and operate all aspects of their business. Instead of an office, each account manager just gets a chair here. Of course, like all insurance, this is a place they hope they will never need.
