Let's close the group and cover group communication in the ACE working
group instead. It is my impression that the train for adding multicast
security to DTLS has left the station already a while ago and folks are
in the meanwhile looking at an application layer security solution instead.

On top of that there are far too few (security) people around so that
the overlap between ACE and DICE is almost 100% anyway. Those who are
interested group security are even a small subset of the security folks
in general (let alone those who have domain expertise in, for example,
the lighting domain).
