I want to know the answer to the following question:
What is the videoconferencing product that both IBM and PictureTel worked on?
All the background I'm provided with is that "Over the next 15 years, Project DIANE (Diversified Information and Assistance Network) grew to utilize a variety of videoconferencing platforms to create a multi-state cooperative public service and distance education network consisting of several hundred schools, neighborhood centers, libraries, science museums, zoos and parks, public assistance centers, and other community oriented organizations.". Is that enough to answer the question?
Answer: no
