In the past day I have resurrected a term I learned two decades ago. Sneaker Net.
sneaker net \ˈsnē-kər ˈnet\ a tongue-in-cheek term used to describe the transfer of electronic information, especially computer files, by physically carrying removable media such as magnetic tape, floppy disks, compact discs, USB flash drives, or external hard drives from one computer to another. This is usually in lieu of transferring the information over a computer network. This mode of data transport is often used as an academic example to illustrate the trade-off between latency and bandwidth. (Ref)
The term nor the definition are original but do represent an effective means for moving data without regard for the large, expensive networks we build.
