I wrote it as a HBcomm plugin, but didn't create a new one. Instead, I modified the ucast plugin so I could patch Heartbeat to fit our needs. Anyway, I guess it wouldn't be hard to make a specific MAC-based ucast plugin for that kind of use, although Heartbeat would have to depend on libpcap from now on.
