FedExing Floppy Disks

From Cory Doctorow’s introduction to the 20th Anniversary edition of The Difference Engine, by William Gibson and Bruce Sterling

… This is the age of collaboration, an era in which it is simpler to work together than ever before. Consider that Bill and Bruce wrote this book by FedExing floppy disks to each other, from Vancouver to Austin and back again, augmented by long, thoughtful faxes debating what should happen next, and compare this to the process by which writers today collaborate. Charlie Stross and I are writing a novel together by loading text into version control systems that instantaneously collate and track all the changes either of us makes.

Freaking. Cool.
