The first steps I think, are going to be transporting huge amounts of data, without wires, and probably pretty damn untraceable. If you can toggle a few bits between two points really fast, you have the ultimate in wireless communication.
From there springs transporting molecules, then up and up till they start transferring mice and monkeys.
Crazy stuff. I wonder if we'll really see this in our lifetimes. Probably just after VCOOK dies it will come out, so he'll still have to deal with UPS fucking up his packages.
