A "new" NSF report on nanotechnology's societal implications is available on-line in two volumes. The work stems from an NSF-sponsored conference held in December 2003. While some of the work here will be familiar - indeed, because the meeting was held three years ago before either CNS was funded, some of the issues might seem a little dated - there are some worthwhile essays. See especially those in Volume 2 which present "individual perspectives" on a range of nano-and-society issues. These include short pieces from a wide range of academics, business people, industry folks, et al..
The reports (along with a similar work stemming from a September 2000 societal implications meeting) can be found at: http://www.wtec.org/SocietalImplications/
