Does anyone know of any kind of reliable wireless video systems, to go from a Macbook Pro to a VGA splitter? I would assume that something is available, at some great expense, but I'm not sure how to begin looking for something like this. The content would be Keynote presentations. I'm not sure of the distance, but I think it's about 30' at most. At this point, this is more of an idea someone had, so budget isn't really important. I'd at least like a minimum price for something of adequate quality. Any ideas.
