Areas are super cool. I was once trying to do similar thing with MVC1. I had two MVC projects in the same solution and the main MVC app referenced the DLL from another mvc app, and along with a bit of MEF magic, I was able to display content from second MVC app in the main MVC application. Couldn't explore further as the took me off bench
I think MVC Areas along with MEF will enable a plugin based web apps where you just drop a DLL and you get all the new menu UI logic working like a magic.
Very nice feature
