I think of it kind of like the early Internet, where you might be able to telnet to one server, then telnet from there to another server, then download a file by FTP to that one, then figure out how to get it from the second telnet server to the first, and then download it at the computer lab and save it to a disk you can carry home because you only have dial-up at home (but meanwhile you can carry on a live phone call with someone in the same room as the original FTP server). #
