I would love to have the ability to run quizzes without an internet connection. For example, I want to use an IPad as the brain where the quiz is projected from, and give the students an iPhone to answer the questions, but without their phones connected to the internet or cellular service. This could be accomplished with either Bluetooth, or through a router with a closed network. As of now, this is not possible, but it would be a huge leap forward for functionality. Also, it would allow more assurance that tech-savvy students are not able to access the internet through the classroom phones without permission.
