3D printing and "Intellectual Property"

A while ago a few of us wrote a paper:

on the "IP" implications of home 3D printing.  This looked at the matter mainly from the UK and EU perspective.

Inspired by that, Public Knowledge, a Washington DC based public interest group, has now put out a white paper on the same questions from a US perspective.  You can access it here:
