Bart, Corosync (http://www.corosync.org) implements The Totem Single Ring Protocol which provides virtual synchrony via a closed process group C programming API. We have full support for native ibverbs/rdmacm infrastructure for RDMA operation. As an aside, it is challenging to bolt in RDMA support into any multicast protocol - good luck to those out there wishing to take this tsak on :) If people would like to see some preliminary benchmarks, mail me off list.
