Testing Portlets in Pluto Portal Driver without Login

Any suggestions on how best to test portlets in Pluto Portal Driver 
1.1.3+ without logging in?  Obviously I can comment out the 
<security-constraint> section in the web.xml and make everything work 
anonymously, but it would be nice to have access to both authenticated 
content and unauthenticated content without reconfiguring and restarting.

The ideal thing would be to have the unauthenticated page contain both 
the login screen and anonymous portlets, and then have different content 
once the user logs in.  I know this would add some complexity to the 
Portal Driver, but I think this is a valid and interesting testing scenario.
