This is really cool. Sun has released Project BlackBox, a "Datacenter in a box", capable of supporting 10,000 simultaneous desktop connections all from a standard shipping container.
I can see this being useful for all kinds of plug-and-play operations, from simple commercial uses to portable military command centers, disaster recovery or disaster assistance.
“Containerization”, using ISO-standard containers, revolutionized the cargo industry. A standard container can fit on a train, boat or truck, anywhere in the world. Using this existing and highly evolved logistics method makes a lot of sense.
