Each of the four discussion groups deliberated over the course of three days of meetings, and produced a report. The objective of each group's report is to briefly summarize the state of the art, the current needs, and articulate a set of research issues and goals.

Additionally, during the discussions with all four groups together, it was unanimously agreed that some elements of infrastructure should also be developed, notably readily available standard fabrication processes, and widely disseminated teaching materials. Thus a fifth group report is included here, briefly addressing the issues of infrastructure.
