Per customer VLAN isolation (common to solve DHCP server issues). You 
can also perform *some* filtering today for multicast addresses, but not 
the specific packets themselves from what I've seen. This is a big 
implementation change. I've had lengthy discussions with the DSLAM 
vendors who said, "VLANs are stupid and as bad as PVCs," about their 
ability to filter RAs and DHCPv6.
