Sounds like a really cool concept I would like to read stories about!
I am thinking in this medium there might be some concern on Story Teller bandwidth in supporting a PC being able to make predictions of the future of plot and such. I won't speak for the Story Teller.
General principals for this medium seem to be chargen that emphasizes socially available characters who will initiate interaction. Anything that enhances that is good. Anything that would tend to shift the initiative to other PC's to initiate is not so good.
