There's a MMO which uses the approach described in the article. Almost everything happens and is stored in memory, in various independent processing units. Data is dumped to disk only occasionally, in case there's complete system failure (so it's more like a backup). I guess they can afford it because losing some progress in a casual game is not very critical.
