I just got my Google Wave invitation today.
Is anyone thinking about ways of using it related to gaming? I can think of some possible uses. Using it to run online games is obvious. There is even already a dice-rolly-thing. For people (like me) who prefer to play around a real table, it would still be a great way to record campaign notes and session write-ups. It would also be a great tool for collaborative campaign/setting design.
Any other ideas?
