Part of open source is the freedom to do whatever you want, of course. Let me ask though; What problems would zookeeper, etcd or other systems solve that can't be solved in corosync? I ask because the HA community just finished a multi-year effort to merge different projects into one common HA stack. This has a lot of benefits to the user base, not least of which is lack of confusion. Strikes me that the significant time investment in supporting a new comms layer would be much more beneficially spent on improving the existing stack. Again, anyone is free to do whatever they want...
