> Many of these same issues were addressed over 15-20 years ago now, by the Internetworking over NBMA (ION) working group. Might be worth revisiting some of the solutions from those days, including MARS, RFC 2022, which emulated IP multicast over unicast or ATM-layer multicast virtual circuits.

Yes I was there. For all of it. Considering all the R&D efforts over that time, what we are doing in LISP is new at the control-plane. At the data-plane there are only 3 ways to achieve forwarding, regular multicast (which BIER is included), head-end-replication, or a combo of both.
