Google and JotSpot

Stewart Mader of Wiki in Education talks with Joe Kraus of JotSpot about their acquisition by Google. Google is becoming the main supplier of software for my students and staff...(Google Earth, SketchUp, Google Docs, Gmail...) This may or may not be a problem in the future, but for now I am getting great tools for my students and teachers with great support, for basically nothing. What I would like to see is some way for me to set up accounts for students on Google Docs without having students register with an email address. I can work around this a bit by using Google hosted GMail, but still it would be nice if they created an education version that allowed a teacher to create and edit accounts. Also it would be nice if a feature set was created that focused on educational uses.
