Interest in adding multicast support to Wireguard?

[Derek Fawcus]

Various routers have support for running PIM (and IGMP/MLD)
in NBMA mode, whereby individual hosts and joins/leave for
such are tracked, rather than depend upon a shared broadcast
medium.

This is used for mcast over Frame Relay, ATM, etc
which are inherently NBMA.

ISTM that wg should also be modelled as NBMA, and as such
the same sorts of approaches should be taken.
