A quizzing use case for Google Wave?

Got on to the surf board and lined up at the edge of the ocean, but not quite sure what to do - seems like a common Google Wave experience for people I know. Perhaps there's one thing we could do - remote quizzing.

It's never been easy to do a live/interactive quiz for people scattered across various locations. Setting up tele-conferences is not an option, which left conferencing on IM, never a stable and pleasant experience. Wave could well be the answer.

With a group of well-behaved participants (how hard will that be to find at a quiz :-)), a moderator should be able to conduct a quiz with people taking turns to answer. Media files can easily be shared, whether on Wave or elsewhere. Wave seems a natural environment to collaborate like this.
