  40. Observations & Conclusions: • Virtual and collaborative design environments have been • at best working prototypes that are too difficult to use as • a day-to-day application. • Better API’s are needed so that scientists, engineers, and • educators can build their own applications based on the • content within their discipline. • The best designed collaborative environments will work • only within existing collaborative groups.
