I was actually thinking more about this today at work (don't tell the boss....)

Dickens published a lot of his work serially. And his stories were wildly popular, like 'Harry Potter' levels of popularity. It seems like the stories of Charles Dickens would work well for this kind of medium; the only problem I came across is that he didn't necessarily serialize each chapter every week, rather, he would serialize 1-3 (-ish) chapters each week. So breaking the story up as he would have broken it up seems the sticking point.

If I ever do this, and it's not against the rules of c/literature, I'll make a post so people can sign up and get stories emailed to them piece by piece :)
