I know some som non-ILECs that do DSL bitstream via L3/MPLS IPVPN and IP
DSLAMs, which then if they implement multicast in their VPN would be able
to provide a service that could support multicast TV.
For me any tunnel based bitstream doesn't scale for the future and in
competetive markets it's already been going away (mostly because ISPs
buying the bitstream service can't compete anyway).
