I don't suppose there is an ad-hoc mode that the ATV2 can create, is there? If so, it would make it absurdly easy to use when traveling or for presentations. I had actually imagined a device that would plug into a projector and streamed presentations/videos from an iPhone. ATV2 could be it, but sadly, I don't think this is a feature. Would need to take along an Airport Express, I think.
