Google appears to bundling several of their apps (gmail, calendar, chat) and promoting them to educational institutions. If I understand the promotion, it appears that institutions are allowed to create an interface that would feature the school logo, etc. as a way to “brand” the site for the school. The sites will feature the familiar google ad words.
This promotion will put Google in competition with companies or initiatives of many institutions to create a portal through which alumni, students, future students, etc. will experience an institution online. Perhaps the approach will appeal to some smaller schools. However, I must admit I wish my institution would offer me the same email capacity, secure browser-based email, and spam control quality as Gmail.
