But those chemical tags are generally multiple, not single molecules. NFC still requires something with a unique radiographic property, so not likely in a single molecule. >> I think we will see larger network segments, but I think we will also see >> greater separation of networks into segments along various administrative >> and/or automatic aggregation boundaries.

Indeed, I think we will end up agreeing to disagree about this, but it will be interesting to see what happens over years to come. I suspect that the answer to which way this goes will be somewhat context sensitive. In some cases, hierarchies will be collapsed. In others, they will expand. Owen
