I am a newbie in web development and just looking into draco. I would be 
interested in some more details about your opinion about draco, before 
going deeper into it.

What is "the MVC way of things"? Is it the Model View Controller design 
pattern? What do you not like about it?

Concerning the relational database for session management, what is so 
icky about that ?

Thanks for your thoughts.
