Sorry for the posting drought. There is a good reason: I'm in the final stages of a textbook based on courses I developed about nanostructures and nanotechnology. It's been an embarrassingly long time in the making, but I'm finally to the index-plus-final-touches stage. I'll say more when it's in to the publisher.
One other thing: I'm going to a 1.5 day workshop at NSF in three weeks about the next steps regarding the NNIN. I've been given copies of the feedback that NSF received in their request for comment period, but if you have additional opinions or information that you'd like aired there, please let me know, either in the comments or via email.
