I agree and IP Multicast is something we can afford on our 44net based networks, which are without NAT and other limits for IPv4 Multicast.
For connecting DMR repeaters between themselves directly, in zero-cong fashion, for instance. Without need for a central DMR master server, which itself is a single point of failure. Its sole role can be to coordinate traffic on talkgroups but the repeater network can learn and communicate directly afterwards. Specially in case of master server failure or network split of any kind.
I am especially interested in repeater linking via amateur IP facilities. As I understand it, most repeater linking is over commercial Internet connections, which is great except that you can't count on them being there in emergencies. Besides, we're hams.
I don't know DMR's IP-level protocols, but if they can be multicast, and the 44-net can support general multicast, that would be a perfect combination.
This is an idea behind a DMR-Multicast project which is already written and I hope I will start testing to release this winter.
Great!
