Phil - another reason for the Controller in that MVC architecture is when
everyone is hitting the web with WML-enabled devices, all you need is to
redirect the WML users to the proper corresponding WML pages for each of the
HTML pages.
This would be a simple code change in the Controller.
If you attempt to control user page flow OUTSIDE of the controller, a change
such as this could be a nightmare to implement.
