Redirecting to different login screens

[Joshua Oransky]

	Is it possible to redirect a user to different login screens based on  
where they try to access ACL'd content? For example, I want to have a  
member area and an admin area of a site. If an anonymous user hits the  
admin area, he should be presented with the admin login screen;  
whereas if the user hits the member area, they get that login instead.
