That's fine with me.

Originally, the check was there to avoid hard coding a specific role in the 
action.  Also, this provides a method of security for Turbine actions as 
well as portlet actions.

I like the idea of using the portlet's security access.  The only question I 
have deals with action events.  Most of the portlets were written before the 
GenericMVCPortlet and GenericMVCAction were created.  To fire 
actions/events, they specify the action on the url.  Because of this, 
Turbine runs the action event before the GenericMVCAction does.  When this 
happens, there is no portlet in the context.  What should be done in this 
case?  Can the security access still be used?
