Cory was talking about this on a podcast from... Worldcon? The big one in Japan last year - and it sounded verra interesting indeed.
Now I have to pick it up. Why can't it be May already? (Because then SIMCON would be over, and it would be spring-like, and no more snow, and I would have new books to read, and could go shooting, and... grrrr, winter can be done now, kthxbai).
