I can hardly imagine how you could have RADIUS and Multicast interact. 
Or then, you'd have to use RADIUS directly on your multicast routers 
(in which VLC won't be involved in access control).

AFAIK, the only way to authenticate access to multicast streams is to 
encrypt the stream and provide the decryption key to authorized users 
via unicast. Of course, then, you must be prepared to the possibility 
that one authorized user "leak" the key to non-authorized users.

But maybe I didn't understand what you mean.
