Well, there's data and then there's data. What if the continuation could 
not be unserialized into anything useful for attacking the server - 
sandboxes are useful for this. I'm not trying to minimize the security 
issue here but there are some real advantages moving closer to a 
peer-to-peer model vs. dumb client/smart server.
