I've been a professional oral tradition storyteller for many years. I've performed before audiences from as large as 5 to 500.
Mind you, I only hit that 500 mark twice, so far.
I'd be hard-pressed to imagine how a device could serve as an adequate replacement for an actual live performance. There are so many little nuances that go into the telling of the oral tradition story that could not be replicated by technology. I have even been fortunate enough to see myself storytelling on several local television channels and sadly I feel that it isn't half as powerful as a live presentation.
Still, the future is evolving - constantly!
