An in-depth interview with CRN's Chris Phoenix has just been posted by NanoMagazine. Chris answers a lot of questions about nanofactory feasibility, and the challenges that remain to develop the technology.
UPDATE: This interview was conducted and published by Sander Olson, one of the original developers of the NanoApex and NanoMagazine web sites. Since the acquisition of those sites in 2005 by the International Small Technology Network, many of Sander's interviews have not been available on the web. To correct this, CRN has begun publishing several of them here.
