I do not agree. For me PID stands at the physical layer, and 13 bits
is not enough to map a multicast IP address.
I would prefer the ethernet scheme, mapping the IP V4 (or V6)
multicast address on the IEEE 48 bits MAC address (link layer).

I do not agree. When you use UDLR (RFC3077) the satellite link behaves
as a broadcast LAN and you can re-use almost everything from the LAN
work.
