I read the http://www.omscs.gatech.edu/faq/ , and found only this hint:
Why is AT&T the corporate collaborator for this initiative?
As a premier global communications company and a champion for innovation in education, AT&T will provide technology access, connectivity and products at inception, as well as evolving service and platform support. The company will serve on an advisory board and, where appropriate, offer corporate projects for credit, be a source from which Georgia Tech draws curriculum content and guest instructors and offer internship opportunities to select students. AT&T will tap into the program to train its own employees and will recruit graduates.
Technology access, connectivity, service and platform support? Aren't those basically solved problems for Udacity?
Advisory board? Does GaTech have corporate sponsorship on the advisory board of their other Master's programs, setting curriculum? (Maybe they should, maybe they shouldn't, but I doubt they think they need to.)
