CNN article about early cornucopia machine development: The machine that can copy anything. Sounds like it isn't too far off production, either.
I wonder how long it will take from the first production model until everyone (yes, everyone) has one? I'm reminded of the spread of potatos and chillis when they first came to Europe - they spread basically everywhere in a few decades, and transport then wasn't as fast.
Also, not too many steps between that and the ones that Stross has in Singularity Sky, I hope.
