I'm going to harp on this (though I don't really see it as harping... more like repping) but I don't see a difference between a storyteller actively being on a scene and GMing (adding another person to the list of people to coordinate times with and also making them THE MOST IMPORTANT PERSON) and that same storyteller crafting a run that can be automated to a degree (the game spits out poses, options, necessary rolls, tracks all that with fail/succeed states and branching paths) so that a group could run it without them needing to be there. Staff could also check a submitted log to make sure the group of runners actually posed and didn't just diddle themselves.
Yes it does remove the possibility of something crazy outside of the box like waiting in the noodle hut next store until the CEO of the MegaCorp who is addicted to General Tsang's Crazy Noodles (info that you acquired outside the current scene) comes in and you ply him with delicious noodles for information... but sacrifices can be made to help a world seem more alive.
At the same time such a system doesn't necessarily kill the idea of a live GMed run. Just another option.
