The Radius element is simply the authenticator. In order to add in
services like billing or pre-payment, the Radius server needs to have
some policies against which it can authenticate.
The Windows 2000 Radius server allows the administrator to assign
policies such as authentication by username, time of day, session limit,
mac address, type of connection e.g. VPN connection or otherwise.
If you want to add a billing option, then that's a policy feature, not
necessarily a Radius feature although a different vendors Radius server
might well present that as an option.
No reason why you can't build this into the Windows 2000 one, in fact it
would be pretty trivial to monitor the session time via a script or
programatically and simply disable the account through an ADSI call to
AD.
